<p>Raise a square matrix to the (integer) power n.</p>
<p>For positive integers n, the power is computed by repeated matrix squarings and matrix multiplications. If n == 0, the identity matrix of the same shape as M is returned. If n &lt; 0, the inverse is computed and then raised to the abs(n).</p>
