DET _ _ _ _ _ _ _ _ _ _ _ _ operator
The det operator returns the determinant of its (square matrix) argument.
<expression> must evaluate to a square matrix.
matrix m,n; m := mat((a,b),(c,d)); M(1,1) := A M(1,2) := B M(2,1) := C M(2,2) := D det m; A*D - B*C n := mat((1,2),(1,2)); N(1,1) := 1 N(1,2) := 2 N(2,1) := 1 N(2,2) := 2 det(n); 0 det(5); 5
Given a numerical argument, det returns the number. Howev er, given a variable name that has not been declared of type matrix, or a non-square matrix, det returns an error message.
