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.
