53<H2>Description</H2>
54<P>This function multiplies a <CODE><A href="VecFx32.html">VecFx32</A></CODE>-type vector by a scalar value and then subtracts another vector from the product. The result is shown by *<em><strong><code>pDest</code></strong></em><CODE> = </CODE><em><strong><code>a</code></strong></em><CODE> x </CODE><em><strong><code>*v1</code></strong></em><CODE> - </CODE><em><strong><code>*v2</code></strong></em>. <em><strong><code>v1</code></strong></em>, <em><strong><code>v2</code></strong></em>, and <em><strong><code>pDst</code></strong></em> can be pointers to the same vector.</P>
