DETERM Function

Standard Library function that calculates the determinant of a square, two-dimensional input variable.

result = DETERM(array)

array An array with two equal dimensions. Can be any data type except string.

result The determinant of the square matrix of array. The result is a scalar value, of either single- or double-precision floating-point data type.

None.

Determinants can be used to evaluate systems of linear equations.

a = INTARR(4,4)
FOR i=0,3 DO a(i,*)=[1,i+2,(i+2)^2,(i+2)^3]
PRINT, a
PRINT, DETERM(a)
