class Eigen::SparseMatrix< _Scalar, _Options, _Index ></h3>
<p>A versatible sparse matrix representation. </p>
<p>This class implements a more versatile variants of the common <em>compressed</em> row/column storage format. Each colmun's (resp. row) non zeros are stored as a pair of value with associated row (resp. colmiun) index. All the non zeros are stored in a single large buffer. Unlike the <em>compressed</em> format, there might be extra space inbetween the nonzeros of two successive colmuns (resp. rows) such that insertion of new non-zero can be done with limited memory reallocation and copies.</p>
<p>A call to the function <a class="el" href="classEigen_1_1SparseMatrix.html#a5daf3de834937aeaa7ebc7f18cea746b">makeCompressed()</a> turns the matrix into the standard <em>compressed</em> format compatible with many library.</p>
<p>More details on this storage sceheme are given in the <a class="el" href="group__TutorialSparse.html">manual pages</a>.</p>

<p>This function is mainly useful for corners where the number of rows is specified at compile time and the number of columns is specified at run time, or vice versa. The compile-time and run-time information should not contradict. In other words, <em>cRows</em> should equal <em>CRows</em> unless <em>CRows</em> is <em>Dynamic</em>, and the same for the number of columns.</p>

<p>Fill the matrix <code>*this</code> with the list of <em>triplets</em> defined by the iterator range <em>begin</em> - <em>end</em>.</p>
<p>A <em>triplet</em> is a tuple (i,j,value) defining a non-zero element. The input list of triplets does not have to be sorted, and can contains duplicated elements. In any case, the result is a <b>sorted</b> and <b>compressed</b> sparse matrix where the duplicates have been summed up. This is a <em>O(n)</em> operation, with <em>n</em> the number of triplet elements. The initial contents of <code>*this</code> is destroyed. The matrix <code>*this</code> must be properly resized beforehand using the <a class="el" href="classEigen_1_1SparseMatrix.html#a400288628e3257a6216b04ba4b2762c7">SparseMatrix(Index,Index)</a> constructor, or the <a class="el" href="classEigen_1_1SparseMatrix.html#ac20f895ce9b73fa7447196855c0d0758">resize(Index,Index)</a> method. The sizes are not extracted from the triplet list.</p>

<p>This function is mainly useful for corners where the number of rows is specified at compile time and the number of columns is specified at run time, or vice versa. The compile-time and run-time information should not contradict. In other words, <em>cRows</em> should equal <em>CRows</em> unless <em>CRows</em> is <em>Dynamic</em>, and the same for the number of columns.</p>
