The operation sequence defines an

where 
<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow>

 is the space corresponding to objects of type <i>Base</i>.
The value 
<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow>
<mi mathvariant='italic'>n</mi>
</mrow></math>

 is the dimension of the 
<a href="seq_property.xml#Domain" target="_top"><span style='white-space: nowrap'>domain</span></a>
 space for the operation sequence.
The value 
<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow>
<mi mathvariant='italic'>m</mi>
</mrow></math>

 is the dimension of the 
<a href="seq_property.xml#Range" target="_top"><span style='white-space: nowrap'>range</span></a>
 space for the operation sequence
(which is determined by the size of <i>y</i>).

<br/>
<br/>
<b><big><a name="f" id="f">f</a></big></b>
<br/>
The object <i>f</i> has prototype
<code><font color="blue"><span style='white-space: nowrap'><br/>
&#xA0;&#xA0;&#xA0;&#xA0;&#xA0;ADFun&lt;</span></font></code><i><span style='white-space: nowrap'>Base</span></i><code><font color="blue"><span style='white-space: nowrap'>&gt;&#xA0;</span></font></code><i><span style='white-space: nowrap'>f</span></i><code><font color="blue"><span style='white-space: nowrap'><br/>
</span></font></code>The AD of <i>Base</i> operation sequence is stored in <i>f</i>; i.e.,
it becomes the operation sequence corresponding to <i>f</i>.
If a previous operation sequence was stored in <i>f</i>,
it is deleted. 

<br/>
<br/>
<b><big><a name="x" id="x">x</a></big></b>
<br/>
The argument <i>x</i> 
must be the vector argument in a previous call to
<a href="independent.xml" target="_top"><span style='white-space: nowrap'>Independent</span></a>
.
Neither its size, or any of its values, are allowed to change
between calling
<code><font color="blue"><span style='white-space: nowrap'><br/>
&#xA0;&#xA0;&#xA0;&#xA0;&#xA0;Independent(</span></font></code><i><span style='white-space: nowrap'>x</span></i><code><font color="blue"><span style='white-space: nowrap'>)<br/>

</span></font></code>.

<br/>
<br/>
<b><big><a name="y" id="y">y</a></big></b>

The vector <i>y</i> has prototype

</span></font></code>(see <a href="funconstruct.xml" target="_top"><span style='white-space: nowrap'>ADvector</span></a>
 below).
The length of <i>y</i> must be greater than zero
and is the dimension of the range space for <i>f</i>.

<br/>
<br/>
<b><big><a name="ADvector" id="ADvector">ADvector</a></big></b>
<br/>
The type <i>ADvector</i> must be a <a href="simplevector.xml" target="_top"><span style='white-space: nowrap'>SimpleVector</span></a>
 class with
<a href="simplevector.xml#Elements of Specified Type" target="_top"><span style='white-space: nowrap'>elements&#xA0;of&#xA0;type</span></a>

<code><font color="blue"><span style='white-space: nowrap'>AD&lt;</span></font></code><i><span style='white-space: nowrap'>Base</span></i><code><font color="blue"><span style='white-space: nowrap'>&gt;</span></font></code>.
The routine <a href="checksimplevector.xml" target="_top"><span style='white-space: nowrap'>CheckSimpleVector</span></a>
 will generate an error message
if this is not the case.

<br/>
<br/>
<b><big><a name="Taping" id="Taping">Taping</a></big></b>
<br/>
The tape,
that was created when <code><font color="blue"><span style='white-space: nowrap'>Independent(</span></font></code><i><span style='white-space: nowrap'>x</span></i><code><font color="blue"><span style='white-space: nowrap'>)</span></font></code> was called, 
will stop recording.
The AD operation sequence will be transferred from
the tape to the object <i>f</i> and the tape will then be deleted.

<br/>
<br/>
<b><big><a name="Forward" id="Forward">Forward</a></big></b>
<br/>
No <a href="forward.xml" target="_top"><span style='white-space: nowrap'>Forward</span></a>
 calculation is preformed during this operation.
Thus, directly after this operation,
<code><font color="blue"><span style='white-space: nowrap'><br/>
&#xA0;&#xA0;&#xA0;&#xA0;&#xA0;</span></font></code><i><span style='white-space: nowrap'>f</span></i><code><font color="blue"><span style='white-space: nowrap'>.size_taylor()<br/>
</span></font></code>is zero (see <a href="size_taylor.xml" target="_top"><span style='white-space: nowrap'>size_taylor</span></a>
).

<br/>
<br/>
<b><big><a name="Example" id="Example">Example</a></big></b>
<br/>
The file
<a href="funcheck.cpp.xml" target="_top"><span style='white-space: nowrap'>FunCheck.cpp</span></a>
 
contains an example and test of this operation.
It returns true if it succeeds and false otherwise.
