int PLASMA_dgeqrf_Tile ( PLASMA_desc *  A,
PLASMA_desc *  T 
)

PLASMA_dgeqrf_Tile - Computes the tile QR factorization of a matrix. Tile equivalent of PLASMA_dgeqrf(). 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 above the diagonal of the array contain the min(M,N)-by-N upper trapezoidal matrix R (R is upper triangular if M >= N); the elements below 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_dgeqrs to solve the system of equations.
Returns:
Return values:
PLASMA_SUCCESS successful exit
