PLASMA_zgetri_Tile - Computes the inverse of a matrix using the LU factorization computed by PLASMA_zgetrf. This method inverts U and then computes inv(A) by solving the system inv(A)*L = inv(U) for inv(A). Tile equivalent of PLASMA_zgetri(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors.
- Parameters
-
[in,out] | A | On entry, the triangular factor L or U from the factorization A = P*L*U as computed by PLASMA_zgetrf. On exit, if return value = 0, the inverse of the original matrix A. |
[in] | IPIV | The pivot indices that define the permutations as returned by PLASMA_zgetrf. |
- Returns
- Return values
-
PLASMA_SUCCESS | successful exit |
>0 | if i, the (i,i) element of the factor U is exactly zero; The matrix is singular and its inverse could not be computed. |
