determinant
Computes the determinant of a square matrix.
The determinant can contain symbolic entries as well as numbers. The direct helper works on a copy of the supplied Matrix, so computing the determinant does not mutate the original matrix.
A non-square matrix does not have a determinant and is rejected.
Examples
These examples use Nerdamer Notation.
Compute the determinant of a 2 by 2 matrix.
determinant(matrix([1,2],[3,4]))
// → -2The determinant of an identity matrix is 1.
determinant(imatrix(3)) // → 1
