Thread: trying to take determinant of matrix using Maple

In Maple I'm trying to take the determinant of a matrix and nothing happens

Code:

> A := matrix([[lambda+1, -2, -3], [-2, lambda+1, -2], [-2, -2, lambda+1]]);

> detA := det(A);
                             det(A)

> B := matrix([[2, 1], [-4, 10]]);
print(`output redirected...`); # input placeholder

> det(B);
                             det(B)

> ans := det(B);
                             det(B)

First you need to load the linear algebra package

with(LinearAlgebra):

The Function Is Determinant(A) not det(A).

Your matrix setup is correct.
