PLASMA_sorglq - Generates an M-by-N matrix Q with orthonormal rows, which is defined as the first M rows of a product of the elementary reflectors returned by PLASMA_sgelqf.
- 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 rows of elementary tile reflectors whose product defines the matrix Q. M >= K >= 0. |
| [in] | A | Details of the LQ factorization of the original matrix A as returned by PLASMA_sgelqf. |
| [in] | LDA | The leading dimension of the array A. LDA >= max(1,M). |
| [in] | descT | Auxiliary factorization data, computed by PLASMA_sgelqf. |
| [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
