Gsl matrix invert

    int s;

    // Compute the LU decomposition of this matrix
    gsl_linalg_LU_decomp(matrix, p, &s);

    // Compute the  inverse of the LU decomposition
    gsl_matrix *inv = gsl_matrix_alloc(size, size);
    gsl_linalg_LU_invert(matrix, p, inv);

    gsl_permutation_free(p);
