The vectors x and y cannot be the same. I.e., one cannot
call <A HREF="../Mat/MatMultTranspose.html#MatMultTranspose">MatMultTranspose</A>(A,y,y).
<P>
For complex numbers this does NOT compute the Hermitian (complex conjugate) transpose multiple,
use <A HREF="../Mat/MatMultHermitianTranspose.html#MatMultHermitianTranspose">MatMultHermitianTranspose</A>()
