<br/>
Fix a memory leak that could occur during the <a href="forsparsejac.xml" target="_top"><span style='white-space: nowrap'>ForSparseJac</span></a>
calculations.
<br/>
<br/>
<b><big><a name="12-23" id="12-23">12-23</a></big></b>
<br/>
The buffers that are used to do
<a href="revsparsejac.xml" target="_top"><span style='white-space: nowrap'>RevSparseJac</span></a>
and <a href="revsparsehes.xml" target="_top"><span style='white-space: nowrap'>RevSparseHes</span></a>
calculations are now freed directly after use.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The <a href="tracknewdel.cpp.xml" target="_top"><span style='white-space: nowrap'>TrackNewDel.cpp</span></a>
example was missing from the Windows install
<a href="installwindows.xml#Examples and Testing" target="_top"><span style='white-space: nowrap'>examples and testing</span></a>
project file.
This has been fixed.
<br/>
<br/>
<b><big><a name="12-22" id="12-22">12-22</a></big></b>
<br/>
The buffer that is are used to do
<a href="reverse.xml" target="_top"><span style='white-space: nowrap'>Reverse</span></a>
mode
calculations is now freed directly after use.
This reduces the memory requirements attached to an <a href="adfun.xml" target="_top"><span style='white-space: nowrap'>ADFun</span></a>
object.
<br/>
<br/>
<b><big><a name="12-20" id="12-20">12-20</a></big></b>
<br/>
Buffers that are used to store the tape information corresponding to
the <code><font color="blue"><span style='white-space: nowrap'>AD<</span></font></code><i><span style='white-space: nowrap'>Base</span></i><code><font color="blue"><span style='white-space: nowrap'>></span></font></code> type are now freed when the corresponding
<a href="adfun.xml" target="_top"><span style='white-space: nowrap'>ADFun</span></a>
object is constructed.
This reduces memory requirements and actually had better results
with the <a href="speed_cppad.xml" target="_top"><span style='white-space: nowrap'>speed_cppad</span></a>
tests.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The <a href="speed_cppad.xml" target="_top"><span style='white-space: nowrap'>speed_cppad</span></a>
test program now outputs the version of CppAD
at the top (to help when comparing output between different versions).
<br/>
<br/>
<b><big><a name="12-19" id="12-19">12-19</a></big></b>
<br/>
The <a href="tracknewdel.xml" target="_top"><span style='white-space: nowrap'>TrackNewDel</span></a>
routines were added for track memory allocation
and deletion with <code><font color="blue">new[]</font></code> and <code><font color="blue">delete[]</font></code>.
This is in preparation for making CppAD more efficient in it's use of
memory.
The bug mentioned on <a href="whats_new_05.xml#12-01" target="_top"><span style='white-space: nowrap'>12-01</span></a>
resurfaced
and the corresponding routine was changed as follows:
<code><font color='blue'><pre style='display:inline'>
static ADTape<Base> *Tape(void)
{ // If we return &tape, instead of creating and returning ptr,
// there seems to be a bug in g++ with -O2 option.
static ADTape<Base> tape;
static ADTape<Base> *ptr = &tape;
return ptr;
}
</pre></font></code>
<br/>
<br/>
<b><big><a name="12-16" id="12-16">12-16</a></big></b>
<br/>
The <a href="nearequal.xml" target="_top"><span style='white-space: nowrap'>NearEqual</span></a>
function documentation for the relative error case
was changed to
<code><font color="blue"><span style='white-space: nowrap'><br/>
     | </span></font></code><i><span style='white-space: nowrap'>x</span></i><code><font color="blue"><span style='white-space: nowrap'> - </span></font></code><i><span style='white-space: nowrap'>y</span></i><code><font color="blue"><span style='white-space: nowrap'> | <= </span></font></code><i><span style='white-space: nowrap'>r</span></i><code><font color="blue"><span style='white-space: nowrap'> * ( |</span></font></code><i><span style='white-space: nowrap'>x</span></i><code><font color="blue"><span style='white-space: nowrap'>| + |</span></font></code><i><span style='white-space: nowrap'>y</span></i><code><font color="blue"><span style='white-space: nowrap'>| )<br/>
</span></font></code>so that there is no problem with division by zero when
<i>x</i> and <i>y</i> are zero
(the code was changed to that form also).
The <code><font color="blue">std::abs</font></code> function replaced the
direct computation of the complex norms
(for the complex case in <code><font color="blue">NearEqual</font></code>).
In addition, more extensive testing was done in <a href="near_equal.cpp.xml" target="_top"><span style='white-space: nowrap'>Near_Equal.cpp</span></a>
.
<br/>
<br/>
<b><big><a name="12-15" id="12-15">12-15</a></big></b>
<br/>
Extend <a href="nearequal.xml" target="_top"><span style='white-space: nowrap'>NearEqual</span></a>
and <a href="nearequalext.xml" target="_top"><span style='white-space: nowrap'>NearEqualExt</span></a>
to cover more cases while converting them from,
a library function in <code><font color="blue">lib/CppADlib.a</font></code>
and an utility in <code><font color="blue">example/NearEqualExt.h</font></code>,
to a template functions in
<code><font color="blue">cppad/near_equal.hpp</font></code> and
<code><font color="blue">cppad/local/NearEqualExt.h</font></code>.
This is another step along the way of removing
the entire <code><font color="blue">CppADlib.a</font></code> library.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The change on <a href="whats_new_05.xml#12-14" target="_top"><span style='white-space: nowrap'>12-14</span></a>
broke the
Microsoft project files <code><font color="blue">example/Example.sln</font></code>
and <code><font color="blue">TestMore/TestMore.sln</font></code> used during CppAD
<a href="installwindows.xml" target="_top"><span style='white-space: nowrap'>installation on Windows</span></a>
.
This has been fixed.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>Move <code><font color="blue">lib/SpeedTest.cpp</font></code> to <code><font color="blue">cppad/speed_test.hpp</font></code>.
This was the last change necessary in order to remove the CppAD library,
so remove all commands related to building and linking <code><font color="blue">CppADlib.a</font></code>.
The corresponding entry has been removed from the <a href="wishlist.xml" target="_top"><span style='white-space: nowrap'>WishList</span></a>
.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>One of the entries in the <a href="wishlist.xml" target="_top"><span style='white-space: nowrap'>WishList</span></a>
corresponded to the
<a href="integer.xml" target="_top"><span style='white-space: nowrap'>Integer</span></a>
function.
It has also been removed (because it is already implemented).
<br/>
<br/>

<br/>
Extend <a href="erf.xml" target="_top"><span style='white-space: nowrap'>erf</span></a>
to cover more cases while converting it
from a function in <code><font color="blue">lib/CppADlib.a</font></code>
to a template function in <code><font color="blue">cppad/local/Erf.h</font></code>.
This is one step along the way of removing
the entire <code><font color="blue">CppADlib.a</font></code> library.
<br/>
<br/>
<b><big><a name="12-11" id="12-11">12-11</a></big></b>
<br/>
Group routines that extend the domain for which an <a href="adfun.xml" target="_top"><span style='white-space: nowrap'>ADFun</span></a>
object is useful into the ExtendDomain section.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>Add an example of a C callable routine that computes
derivatives using CppAD (see <a href="interface2c.cpp.xml" target="_top"><span style='white-space: nowrap'>Interface2C.cpp</span></a>
).
<br/>
<br/>

<br/>
Split out <a href="lufactor.xml" target="_top"><span style='white-space: nowrap'>LuFactor</span></a>
with the <i>ratio</i> argument
to a separate function called <a href="luratio.xml" target="_top"><span style='white-space: nowrap'>LuRatio</span></a>
.
This needed to be done because <a href="luratio.xml" target="_top"><span style='white-space: nowrap'>LuRatio</span></a>
is more restrictive
and should not be part of the general template <a href="library.xml" target="_top"><span style='white-space: nowrap'>library</span></a>
.
<br/>
<br/>
<b><big><a name="12-07" id="12-07">12-07</a></big></b>
<br/>
Improve <a href="checksimplevector.xml" target="_top"><span style='white-space: nowrap'>CheckSimpleVector</span></a>
so that it tests element assignment.
Change <a href="checksimplevector.cpp.xml" target="_top"><span style='white-space: nowrap'>CheckSimpleVector.cpp</span></a>
so that it provides
and example and test of a case where a simple vector returns a type
different from the element type and the element assignment returns
<code><font color="blue">void</font></code>.
<br/>
<br/>
<b><big><a name="12-06" id="12-06">12-06</a></big></b>
<br/>
The specifications for a <a href="simplevector.xml" target="_top"><span style='white-space: nowrap'>SimpleVector</span></a>
template class
were extended so that the return type of an element access is
not necessarily the same as the type of the elements.
This enables us to include <code><font color="blue">std::vector<bool></font></code>
which packs multiple elements into a single storage location
and returns a special type on element access (not the same as <code><font color="blue">bool</font></code>).
To be more specific,
if <i>x</i> is a <code><font color="blue">std::vector<bool></font></code> object
and <i>i</i> has type <code><font color="blue">size_t</font></code>,
<code><font color="blue"></font></code><i><span style='white-space: nowrap'>x</span></i><code><font color="blue"><span style='white-space: nowrap'>[</span></font></code><i><span style='white-space: nowrap'>i</span></i><code><font color="blue"><span style='white-space: nowrap'>]</span></font></code> does not have type <code><font color="blue">bool</font></code>.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>Add a Home icon,
that links to the
<a href="http://www.coin-or.org/CppAD/" target="_top"><span style='white-space: nowrap'>CppAD home page</span></a>
,
to the top left of the navigation frame
(left frame) for each documentation section.

The <a href="revsparsehes.xml" target="_top"><span style='white-space: nowrap'>RevSparseHes</span></a>
reverse mode Hessian sparsity calculation
has been added.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The definition of a <a href="glossary.xml#Sparsity Pattern" target="_top"><span style='white-space: nowrap'>sparsity pattern</span></a>
has been corrected to properly correspond to the more efficient form
mentioned under <a href="whats_new_05.xml#11-20" target="_top"><span style='white-space: nowrap'>whats_new_05</span></a>

There was a bug in the <a href="revsparsejac.xml" target="_top"><span style='white-space: nowrap'>RevSparseJac</span></a>
reverse mode sparsity patterns when used with <a href="vecad.xml" target="_top"><span style='white-space: nowrap'>VecAD</span></a>

(fewer true entries).

<br/>
The speed test of <a href="luvecad.xml" target="_top"><span style='white-space: nowrap'>LuVecAD</span></a>
has been reinstated.
It appears that there is some sort of bug in the gcc compiler with
the -O2 option whereby the following member function
<code><font color='blue'><pre style='display:inline'>
static ADTape<Base> *Tape(void)
{ static ADTape<Base> tape;
return &tape;
}
</pre></font></code>
(in <code><font color="blue">cppad/local/AD.h</font></code>)
would sometimes return a null value (during <a href="vecad.xml" target="_top"><span style='white-space: nowrap'>VecAD</span></a>
operations).
A speed improvement in
<code><font color="blue">cppad/local/ExtendBuffer.h</font></code> seems to prevent
this problem.
This fix is not well understood; i.e., we should watch to see
if this problem reoccurs.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The source code for
<a href="luvecadok.cpp.xml" target="_top"><span style='white-space: nowrap'>LuVecADOk.cpp</span></a>
was mistakenly used for
<code><font color="blue">speed_cppad/LuSolveSpeed.cpp</font></code>.
This has been fixed.
<br/>
<br/>
<b><big><a name="11-23" id="11-23">11-23</a></big></b>
<br/>
The speed test of <a href="luvecad.xml" target="_top"><span style='white-space: nowrap'>LuVecAD</span></a>
has been commented out
because it sometimes generates a segmentation fault.
Here is an explanation:
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>If <i>X</i> is a <code><font color="blue"><span style='white-space: nowrap'>AD<</span></font></code><i><span style='white-space: nowrap'>Base</span></i><code><font color="blue"><span style='white-space: nowrap'>></span></font></code> object,
<i>y</i> is a <i>Base</i> object,
<code><font color="blue"></font></code><i><span style='white-space: nowrap'>X</span></i><code><font color="blue"><span style='white-space: nowrap'>[</span></font></code><i><span style='white-space: nowrap'>y</span></i><code><font color="blue"><span style='white-space: nowrap'>]</span></font></code> uses pointer from the element
back to the original vector.
Optimizing compilers might reorder operations so that
the vector is destroyed before the object is used.
This can be avoided by changing the syntax for <a href="vecad.xml" target="_top"><span style='white-space: nowrap'>VecAD</span></a>
objects
to use <code><font color="blue">set</font></code> and <code><font color="blue">get</font></code> member functions.
<br/>
<br/>
<b><big><a name="11-22" id="11-22">11-22</a></big></b>
<br/>
A much better <a href="vec_ad.cpp.xml" target="_top"><span style='white-space: nowrap'>example</span></a>
for using <a href="vecad.xml" target="_top"><span style='white-space: nowrap'>VecAD</span></a>
vectors has been provided. In addition, a bug
in the computation of derivatives using <code><font color="blue">VecAD</font></code> vectors
has been fixed.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>CppAD now checks that the domain dimension during
<a href="independent.xml" target="_top"><span style='white-space: nowrap'>Independent</span></a>
and
the range dimension during <a href="adfun.xml" target="_top"><span style='white-space: nowrap'>ADFun</span></a>
(provided that <code><font color="blue">-DNDEBUG</font></code> is not defined).
If either of these is zero,
the <code><font color="blue">CppADUsageError</font></code> macro is invoked.
<br/>
<br/>
<b><big><a name="11-20" id="11-20">11-20</a></big></b>
<br/>
The sparsity pattern routines
<a href="forsparsejac.xml" target="_top"><span style='white-space: nowrap'>ForSparseJac</span></a>
and <a href="revsparsejac.xml" target="_top"><span style='white-space: nowrap'>RevSparseJac</span></a>
have been modified so that they are relative
to the Jacobian at a single argument value.
This enables us to return more efficient
<a href="glossary.xml#Sparsity Pattern" target="_top"><span style='white-space: nowrap'>sparsity patterns</span></a>
.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>An extra <a href="vecad.xml#VecAD<Base>::reference.Exceptions" target="_top"><span style='white-space: nowrap'>exception</span></a>
has been
added to the use of <a href="vecad.xml" target="_top"><span style='white-space: nowrap'>VecAD</span></a>
elements.
This makes <code><font color="blue">VecAD</font></code> some what more efficient.

</span></code>The copy base section was split into the <a href="default.xml" target="_top"><span style='white-space: nowrap'>default</span></a>
constructor and the
construction for the base type.
The construction from base type has been
extended to include any type that is convertible to the base type.
As a special case, this provides the previous wish list item of
a constructor from an arbitrary <i>Base</i> to a
<code><font color="blue"><span style='white-space: nowrap'>AD< AD<</span></font></code><i><span style='white-space: nowrap'>Base</span></i><code><font color="blue"><span style='white-space: nowrap'>> ></span></font></code>, <code><font color="blue"><span style='white-space: nowrap'>AD< AD< AD<</span></font></code><i><span style='white-space: nowrap'>Base</span></i><code><font color="blue"><span style='white-space: nowrap'>> > ></span></font></code> etc.

The changes made on 06-06 do not run under Microsoft Visual C++ version 6.0
(even though they are within the C++ standard).
Preliminary testing under version 7 indicates that Microsoft
has fixed this problem in later versions of their C++ compiler.

A significant improvement in speed was obtained by moving
the buffer extension to a separate function and then
inline the rest of putting operators in the tape.
For example,
here is part of the speed test output before this change:
<code><font color='blue'><pre style='display:inline'>
Tape of Expansion by Minors Determinant: Length = 350, Memory = 6792
size = 5 rate = 230
size = 4 rate = 1,055
size = 3 rate = 3,408
size = 2 rate = 7,571
size = 1 rate = 13,642
</pre></font></code>
and here is the same output after this change:
<code><font color='blue'><pre style='display:inline'>
Tape of Expansion by Minors Determinant: Length = 350, Memory = 6792
size = 5 rate = 448
size = 4 rate = 2,004
size = 3 rate = 5,761
size = 2 rate = 10,221
size = 1 rate = 14,734
</pre></font></code>

The profiling indicated that the destructor for an AD object was using a
significant amount of time.
The internal data structure of an AD object had a doubly linked list
that pointed to the current variables and this was modified when
an AD object was destroyed.
In order to speed AD operations in general,
the internal data structure of an AD object has been changed so that
this list is no longer necessary (a tape id number is used in its place)
<code><span style='white-space: nowrap'><br/>
