Determinant of a matrix

[Dan, Ho-Jin]

You can decompose a symmetric matrix L D L^T which is not singular, 
where the value
of diagonal elements of L  is one. The determinamt of a matrix can be 
calculated by the
multiplication of all elements of  D. If a matrix is singular, the 
determinant is zero as you know.
I think this method is correct and can be generalized unsymmetric matirx.
But I'm not sure that this is the most efficient.

Please *check* the algebra text. I have no reference at near hand now.
