DET

Syntax: DET [array]
Location: Math Package

The function DET returns the determinant of a square matrix, meaning that the array (or the part passed) must have two dimensions of equal size, otherwise DET breaks with error -15 (bad parameter). The array needs to be a floating point array.  If no parameter is given, DET will use the array that has been supplied to the previously executed MATINV command as its source.

CROSS-REFERENCE:
MATINV co-operates closely with DET, so that for each of them a matrix parameter can be omitted if the other function has been called before; MATINV calls DET internally.
See the MATRND, MATIDN, SGN and MATSUB keywords which are all part of the same Toolkit.
