DETERM Function
Standard Library function that calculates the determinant of a square, two-dimensional input variable.
Usage
result = DETERM(array)
Input Parameters
array — Array with two equal dimensions. Can be any data type except string.
Returned Value
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.
Keywords
None.
Discussion
Determinants can be used to evaluate systems of linear equations.
Example
a = INTARR(4, 4)
FOR i=0L,3 DO a(i,*) = [1, i+2, (i+2)^2, (i+2)^3]
PRINT, a
; PV-WAVE prints:
; 1 1 1 1
; 2 3 4 5
; 4 9 16 25
; 8 27 64 125
PRINT, DETERM(a)
; PV-WAVE prints:
; 12.0000
