Matrix determinant

Syntax: a = DET(m)

The function DET(m) returns the determinant of the matrix m, which must be a square matrix. The output is a scalar.

Beware: The determinant of a reasonably sized matrix can get very large, or very small, leading to over/underflows.

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 INVERSE function section.
