<h4>Description</h4>
|
||
|
|
<p>The templated class <code>matrix<T, F, A></code> is the
|
||
|
|
base container adaptor for dense matrices. For a <em>(m x
|
||
|
|
n</em>)-dimensional matrix and <em>0 <= i < m</em>, <em>0
|
||
|
|
<= j < n</em> every element <em>m</em><sub><em>i,
|
||
|
|
j</em></sub> is mapped to the <em>(i x n + j)-</em>th element of
|
||
|
|
the container for row major orientation or the <em>(i + j x
|
||
|
|
m)-</em>th element of the container for column major
|
||
|
|
orientation.</p>
