PLASMA_cgelqf - Computes the tile LQ factorization of a complex M-by-N matrix A: A = L * Q.
- Parameters:
-
[in] | M | The number of rows of the matrix A. M >= 0. |
[in] | N | The number of columns of the matrix A. N >= 0. |
[in,out] | A | On entry, the M-by-N matrix A. On exit, the elements on and below the diagonal of the array contain the m-by-min(M,N) lower trapezoidal matrix L (L is lower triangular if M <= N); the elements above the diagonal represent the unitary matrix Q as a product of elementary reflectors, stored by tiles. |
[in] | LDA | The leading dimension of the array A. LDA >= max(1,M). |
[out] | T | On exit, auxiliary factorization data, required by PLASMA_cgelqs to solve the system of equations. |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
| <0 | if -i, the i-th argument had an illegal value |
