Matrices in matlab

  1. Dec 11, 2007 #1
    i have a matrix:
    A=[2 1 1 1; 6 2 4 3; 8 -1 -3 4; 10 0 2 5]
    i have to find the determinant by doing a laplace expansion with respect to the last row.
    how do i do this on matlab.
    can someone please tell me what to write on the mfile.
    thank you

    To find the determinant, just use det(A)
