PLASMA_sormqr_Tile - overwrites the general M-by-N matrix C with Q*C, where Q is an orthogonal matrix (unitary in the complex case) defined as the product of elementary reflectors returned by PLASMA_sgeqrf_Tile Q is of order M. All matrices are passed through descriptors. All dimensions are taken from the descriptors.
- Parameters:
-
[in] | side | Intended usage: = PlasmaLeft: apply Q or Q\*\*T from the left; = PlasmaRight: apply Q or Q\*\*T from the right. Currently only PlasmaLeft is supported. |
[in] | trans | Intended usage: = PlasmaNoTrans: no transpose, apply Q; = PlasmaTrans: ugate transpose, apply Q\*\*T. Currently only PlasmaTrans is supported. |
[in] | A | Details of the QR factorization of the original matrix A as returned by PLASMA_sgeqrf. |
[in] | T | Auxiliary factorization data, computed by PLASMA_sgeqrf. |
[in,out] | B | On entry, the M-by-N matrix B. On exit, B is overwritten by Q*B or Q\*\*T*B. |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
