  21 <p>This header introduces specializations of the <i><span class="RenoLink"><a href="vec_traits.html">vec_traits</a></span></i>, <i><span class="RenoLink"><a href="deduce_vec.html">deduce_vec</a></span></i> and <i><span class="RenoLink"><a href="deduce_vec2.html">deduce_vec2</a></span></i> templates that make it possible to pass C arrays to any Boost QVM function that takes a vector of matching size.</p>
  22 <div class="RenoIncludeDIV"><p>For example, after <i>#include &lt;<span class="RenoLink">boost/qvm/vec_traits_array.hpp</span>&gt;</i>, to compute the dot product of two C arrays, you could use:</p>
  23 <pre>float a[4], b[4];
  24 float dp = <span class="RenoLink"><a href="dot_vec_vec_.html">dot</a></span>(a,b);</pre>
  25 <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 vector by a scalar by using <i><span class="RenoLink"><a href="operator_mul_eq_vec_scalar_.html">operator*=</a></span></i> directly. Use <i><span class="RenoLink"><a href="vref.html">vref</a></span></i> to work around this issue:</p>
  26 <pre>float a[4];
  27 <span class="RenoLink"><a href="vref.html">vref</a></span>(a) <span class="RenoLink"><a href="operator_mul_eq_vec_scalar_.html">*=</a></span> 42;</pre>
