<p>This header introduces specializations of the <i><span class="RenoLink"><a href="mat_traits.html">mat_traits</a></span></i>, <i><span class="RenoLink"><a href="deduce_mat.html">deduce_mat</a></span></i> and <i><span class="RenoLink"><a href="deduce_mat2.html">deduce_mat2</a></span></i> templates that make it possible to pass 2D C arrays to any Boost QVM function that takes a matrix of matching size.</p>
|
|
<div class="RenoIncludeDIV"><p>For example, after <i>#include <<span class="RenoLink">boost/qvm/mat_traits_array.hpp</span>></i>, to compute the determinant of a square 2D C array matrix, you can use:</p>
|
|
<pre>float a[4][4];
|
|
float det = <span class="RenoLink"><a href="determinant.html">determinant</a></span>(a);</pre>
|
|
<p>To use Boost QVM operator overloads, at least one of the arguments must not be of a built-in type; for example, you can't multiply a C array matrix by a scalar by using <i><span class="RenoLink"><a href="operator_mul_eq_mat_scalar_.html">operator*=</a></span></i> directly. Use <i><span class="RenoLink"><a href="mref.html">mref</a></span></i> to work around this issue:</p>
|
|
<pre>float a[4][4];
|
|
<span class="RenoLink"><a href="mref.html">mref</a></span>(a) <span class="RenoLink"><a href="operator_mul_eq_mat_scalar_.html">*=</a></span> 42;</pre>
