Invert a 9x9 Matrix in DSP of TI Concerto F28M35x

I am trying to compute the determinant and inverse of a 9x9 matrix. Could you point me to the right library. I am using TI Concerto F28M35x.

    Hi Rohan,

    Unfortunately, we dont have a library for matrix operations. To do the matrix inversion, you can search for Gaussian elimination algorithms, there seem to be open-source versions available. Numerical recipes in C, 2nd edition has one as well.

    And for determinant, i think you need to do an LU decomposition of the original matrix, and then just multiply the diagonals of the upper triangular matrix to get the determinant. Again, the LU decomp C code is available online and in the numerical recipes book.
