PLASMA_sgetrf_Tile - Computes the tile LU factorization of a matrix. Tile equivalent of PLASMA_sgetrf(). 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 M-by-N matrix to be factored. On exit, the tile factors L and U from the factorization. |
[out] | L | On exit, auxiliary factorization data, related to the tile L factor, required by PLASMA_sgetrs to solve the system of equations. |
[out] | IPIV | The pivot indices that define the permutations (not equivalent to LAPACK). |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
| >0 | if i, U(i,i) is exactly zero. The factorization has been completed, but the factor U is exactly singular, and division by zero will occur if it is used to solve a system of equations. |
