PLASMA_sorgqr - Generates an M-by-N matrix Q with orthonormal columns, which is defined as the first N columns of a product of the elementary reflectors returned by PLASMA_sgeqrf.
- Parameters:
-
[in] | M | The number of rows of the matrix Q. M >= 0. |
[in] | N | The number of columns of the matrix Q. N >= M. |
[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. |
[out] | Q | On exit, the M-by-N matrix Q. |
[in] | LDQ | The leading dimension of the array Q. LDQ >= max(1,M). |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
| <0 | if -i, the i-th argument had an illegal value |
