    So is this a maths question or a coding question?

    maths:
    http://www.google.com/search?q=matrix+inversion

    code:
    int matrix[5][5];
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Lightbulb Something to keep in mind.

    Not all matrices are invertible. One simple test to see if a matrix is invertible is by using the determinant. If the determinant is nonzero, it is invertible.

    I don't know how to code this, but I can give information on how an inverse is found....

    If you take your matrix and perform a series of operations on it to transform it to the identity matrix and then perform the exact same operations in the exact same order on the identity matrix, the matrix formed will be the inverse of the original.
