Matrix of ODE's in MATLAB

  1. Aug 2, 2006 #1
    Hey all,

    Consider the system [tex]X' = f(X)[/tex], where [tex]X[/tex] is a square matrix. I would like to solve this system with MATLAB, but all of its solvers require [tex]X[/tex] to be a column vector.

    Of course, it would be possible to rewrite [tex]X'[/tex] and [tex]f(X)[/tex] as column vectors, but I guess some efficiency would be lost. It would also be a lot of pain to do :grumpy:

    So, does anyone know of a simpler way to do such a thing? Thank you!!

    It's not a pain to do with the reshape command.

    :shy: Why on earth didn't I think of that? You can't possibly imagine how much that just helped me! Thank you very much!!
