 Define the following matrices:</P>

   m1 = <code>3&times;4</code> matrix of zeroes<br />
   m2 = the <code>3&times;3</code> matrix where row1<code>=(1,2,0)</code>,
    row2<code>=(2,5,-1)</code>, row3<code>=(4,10,-1)</code><br />
   m3 = transpose of m2<br />
   m4 = dot product of m2 and m3<br />
   m5 = sum of m2 and m3<br />
   m6 = elementwise product of m2 and m3<br />
   m7 = matrix inverse of m2<br />
   m8 = the <code>5&times;5</code> identity matrix</P>
