PLASMA_sormqr - 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. Q is of order M.
- 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] | M | The number of rows of the matrix C. M >= 0. |
[in] | N | The number of columns of the matrix C. N >= 0. |
[in] | K | The number of columns of elementary tile reflectors whose product defines the matrix Q. M >= K >= 0. |
[in] | A | Details of the QR factorization of the original matrix A as returned by PLASMA_sgeqrf. |
[in] | LDA | The leading dimension of the array A. LDA >= max(1,M); |
[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. |
[in] | LDB | The leading dimension of the array C. LDC >= max(1,M). |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
| <0 | if -i, the i-th argument had an illegal value |
