int PLASMA_zgeqrf_Tile ( PLASMA_desc *  A, PLASMA_desc *  T  ) PLASMA_zgeqrf_Tile - Computes the tile QR factorization of a matrix. Tile equivalent of PLASMA_zgeqrf(). 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_zgeqrs to solve the system of equations. Returns Return values PLASMA_SUCCESS successful exit See Also PLASMA_zgeqrf PLASMA_zgeqrf_Tile_Async PLASMA_cgeqrf_Tile PLASMA_dgeqrf_Tile PLASMA_sgeqrf_Tile PLASMA_zgeqrs_Tile
