<p>Resizes <code>*this</code> to a <em>rows</em> x <em>cols</em> matrix.</p>
<p>This method is intended for dynamic-size matrices, although it is legal to call it on any matrix as long as fixed dimensions are left unchanged. If you only want to change the number of rows and/or of columns, you can use <a class="el" href="classEigen_1_1PlainObjectBase.html#aec9ca3c51c341a06bce3451ff1adc84d">resize(NoChange_t, Index)</a>, <a class="el" href="classEigen_1_1PlainObjectBase.html#a58d9d13dd3982d05458767072c257886">resize(Index, NoChange_t)</a>.</p>
<p>If the current number of coefficients of <code>*this</code> exactly matches the product <em>rows</em> * <em>cols</em>, then no memory allocation is performed and the current values are left unchanged. In all other cases, including shrinking, the data is reallocated and all previous values are lost.</p>
