PLASMA_zgeqrs - Compute a minimum-norm solution min || A*X - B || using the RQ factorization A = R*Q computed by PLASMA_zgeqrf.
- Parameters:
-
[in] | M | The number of rows of the matrix A. M >= 0. |
[in] | N | The number of columns of the matrix A. N >= M >= 0. |
[in] | NRHS | The number of columns of B. NRHS >= 0. |
[in,out] | A | Details of the QR factorization of the original matrix A as returned by PLASMA_zgeqrf. |
[in] | LDA | The leading dimension of the array A. LDA >= M. |
[in] | T | Auxiliary factorization data, computed by PLASMA_zgeqrf. |
[in,out] | B | On entry, the m-by-nrhs right hand side matrix B. On exit, the n-by-nrhs solution matrix X. |
[in] | LDB | The leading dimension of the array B. LDB >= max(1,N). |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
| <0 | if -i, the i-th argument had an illegal value |
