<p> The function checks to make sure that the input and output matrices are of the same size.</p>
<p>In the fixed-point Q15 and Q31 functions, <code>scale</code> is represented by a fractional multiplication <code>scaleFract</code> and an arithmetic shift <code>shift</code>. The shift allows the gain of
