Create a <code>10×3</code> array <code>A</code> where the first column are the
<code>x</code> values <code>1</code>
through <code>10</code>, the second column are the <code>y</code> values where
<code>y(x) = sqrt(x)</code> and the third column are the <code>z</code> values where
<code>z = x^2</code>. Write the values of <code>A</code> to file <code>A.dat</code>,
one row per line. Generate a <code>7×11</code> matrix <code>R</code> of random
values (uniform on <code>[0,1]</code>), and write this matrix to file
<code>ranm.dat</code>.</P>
