Using Prime 3.0, the determinant function does not handle a matrix with complex numbers. Don't how to fix it.

When I load a matrix up with al reals the |A| or det(A) works fine and returns the value.  If I add a +1i or any imaginary number to an element, the |A| or det(A) returnb 0.  This frustrating since I have programs that use this alot for filling arrays in a linear systems problem.
