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.
