  1. How do I differentiate two matricies with HP 50G or HP 49G?

    Hello,

    i have a question to a matrix operation with the HP 50G and/or HP 49G.
    How do I differentiate two matricies? I donīt mean "matrix minus
    matrix"!

    Example:

    [[1,2,3,4][5,6,7,8][1,2,3,4][5,6,7,8]]->a

    delta(a) = [[4,4,4,4][-4,-4,-4,-4][4,4,4,4]]


    Is there a possibility? With the TI-89 that is possible!

    I assume you mean:
    [[Row2-Row1][Row3-Row2][Row4-Row3]]

    > [[1,2,3,4][5,6,7,8][1,2,3,4][5,6,7,8]]->a


    If this matrix is on the stack then this program should work:

    \<< AXM 2 \<< SWAP - \>> DOSUBS AXM \>>

    Unfortunately that does not function! I tried it several times.

    Oops! My bad, it should have been:

    \<< AXL 2 \<< SWAP - \>> DOSUBS AXL \>>

    Thank you, Robert!!

    It works!
