PLASMA_dgelqf_Tile - Computes the tile LQ factorization of a matrix. Tile equivalent of PLASMA_dgelqf(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors.
- Parameters:
-
[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. |
[out] | T | On exit, auxiliary factorization data, required by PLASMA_dgelqs to solve the system of equations. |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
