1. ## Determinant of a 2 x 3 matrix?

How to you calculate the determinant of a 2 x 3 matrix? What would the determinant of this be?:

[1 3 5]
[2 4 6]

Thanks greatly, Jim

2. You can't. Determinants are only defined for square matrices.

3. Unless there is some exotic generalization of the determinant to the m x n case, as far as I know you can only compute determinants for n x n, i.e. square, matrices.

4. Thanks guys, thats what I thought.
