    How to do Cross Product of Two 3x3 Matrices

    How do I take the cross product of Two 3x3 Matrices.

    For example what is cross product of:
    [-1 0 0]
    [0 1 0]
    [0 0 1]

    x

    [0 -1 0]
    [1 0 0]
    [0 0 1]

    thanks,

    i've seen that the Lie bracket of two matrices of the same size A, B, which is defined by [A, B] = AB - BA, sometimes is called the cross product of A, B.
