MXM_SERIAL <br> Matrix Multiplication
</h1>
<hr>
<p>
<b>MXM_SERIAL</b>
is a C++ program which
sets up a dense matrix multiplication problem C = A * B.
</p>
<p>
The matrices A and B are chosen so that C = (N+1) * I,
where N is the order of A and B, and I is the identity matrix.
</p>
<p>
<b>MXM_SERIAL</b> is intended as a starting point for the implementation of a
parallel version, using, for instance, OpenMP.
