PLASMA_cpotrf_Tile - Computes the Cholesky factorization of a symmetric positive definite or Hermitian positive definite matrix. Tile equivalent of PLASMA_cpotrf(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors.
- Parameters:
-
[in] | uplo | = PlasmaUpper: Upper triangle of A is stored; = PlasmaLower: Lower triangle of A is stored. |
[in] | A | On entry, the symmetric positive definite (or Hermitian) matrix A. If uplo = PlasmaUpper, the leading N-by-N upper triangular part of A contains the upper triangular part of the matrix A, and the strictly lower triangular part of A is not referenced. If UPLO = 'L', the leading N-by-N lower triangular part of A contains the lower triangular part of the matrix A, and the strictly upper triangular part of A is not referenced. On exit, if return value = 0, the factor U or L from the Cholesky factorization A = U\*\*H*U or A = L*L\*\*H. |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
| >0 | if i, the leading minor of order i of A is not positive definite, so the factorization could not be completed, and the solution has not been computed. |
