int PLASMA_dgelqf_Tile ( PLASMA_desc *  A,
PLASMA_desc *  T 
)

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
