<p><em>Note:</em> The last argument (<code>bool init</code>) of

<p><em>Note:</em> The blocksize can be any integer. However, the
-total speed depends very strong on the combination of blocksize,
+actual speed depends very significantly on the combination of blocksize,
CPU and compiler. The function <code>block_prod</code> is designed
for large dense matrices.</p>
