PLASMA_dtrtri_Tile - Computes the inverse of a complex upper or lower triangular matrix A. Tile equivalent of PLASMA_dtrtri(). 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] | diag | = PlasmaNonUnit: A is non-unit triangular; = PlasmaUnit: A us unit triangular. |
[in] | A | On entry, the triangular matrix A. If UPLO = 'U', the leading N-by-N upper triangular part of the array A contains the upper triangular matrix, and the strictly lower triangular part of A is not referenced. If UPLO = 'L', the leading N-by-N lower triangular part of the array A contains the lower triangular matrix, and the strictly upper triangular part of A is not referenced. If DIAG = 'U', the diagonal elements of A are also not referenced and are assumed to be 1. On exit, the (triangular) inverse of the original matrix, in the same storage format. |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
| >0 | if i, A(i,i) is exactly zero. The triangular matrix is singular and its inverse can not be computed. |
