int  LDA,
float *  T 
)

PLASMA_sgelqf - 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_sgelqs to solve the system of equations.
Returns:
Return values:
PLASMA_SUCCESS successful exit
<0 if -i, the i-th argument had an illegal value
