Hello, i need help in implementing large matrix decomposition.

i will be using a 9 by 9 matrix.

i am using directxMath as my matrix manipulation/calculation class, but it operates only with 4x4 Matrices.

Any chance anyone has a simple solution for this? or at least simplified implementation.

I did not really understand the *Gauss-Jordan method. i found an example with a 3x3 matrix, but i could not really get my head around how to implement it on a bigger matrix...*

*Then there is a method *Inverse of a Matrix using Minors, Cofactors and Adjugate, which looked like a nightmare.

Any help appreciated , thanks!
