<p>
The function <CODE>DET(m)</code> returns the determinant
of the matrix <CODE>m</code>, which <i>must</i> be a square matrix. The output is a scalar.</p>
<p>
<i>Beware</i>: The determinant of a reasonably sized matrix can get very large,
or very small, leading to over/underflows.</p>
<p>
The method used to find the determinant uses the LU decomposition of the
matrix argument. Please refer to the discussion on LU decomposition of a
matrix in the <CODE><a href="../Inverse/inverse.htm">INVERSE</a></code> function section.</p>
