DET 

The DET function returns the determinant of a square numeric matrix.  If
the matrix is DECIMAL or SHORT DECIMAL, HP Business BASIC/XL converts it
to REAL before computing the determinant.  The result is of the default
numeric type.

Syntax 

DET(num_sq_matrix)

Parameters 

num_sq_matrix    A two dimensional numeric array with the same number of
                 rows as columns.
