Maple -> C translation of solving for square root of a matrix?

    Hi all,

    I am trying to use Maple -> C translation facility for a special use:

    I need a matrix square root function in C/C++.

    I only need it for 3x3 matrix, so I decide to find some hard-coded piece of
    program, instead of using some numerical library, because then I have to
    learn some new API and how to link and how to use stuff.

    To avoid the trouble, I think a 3x3 hard-coded program is sufficient for me.
    That's to say, given M a 3x3 matrix, I want to find M^(0.5) in C/C++.

    I tried Maple, but it seems strange:

    I gave it a simple 3x3 matrix, and used "MatrixPower" function.

    After half an our or more, it says "output exceed 1000000 lines".

    So I didn't continue, I am afraid that even I get it translated to C/C++, it
    will be a huge piece of the code and actually a mess...

    Any thoughts on that?

  2. The problem is probably the datatype.

    The following works fine.


    and so does this,
