PLASMA_cungqr - Generates an M-by-N matrix Q with orthonormal columns, which is defined as the first N columns of a product of the elementary reflectors returned by PLASMA_cgeqrf.

Parameters

[in]	M	The number of rows of the matrix Q. M >= 0.
[in]	N	The number of columns of the matrix Q. N >= M.
[in]	K	The number of columns of elementary tile reflectors whose product defines the matrix Q. M >= K >= 0.
[in]	A	Details of the QR factorization of the original matrix A as returned by PLASMA_cgeqrf.
[in]	LDA	The leading dimension of the array A. LDA >= max(1,M).
[in]	descT	Auxiliary factorization data, computed by PLASMA_cgeqrf.
[out]	Q	On exit, the M-by-N matrix Q.
[in]	LDQ	The leading dimension of the array Q. LDQ >= max(1,M).

Returns

Return values

PLASMA_SUCCESS	successful exit
<0	if -i, the i-th argument had an illegal value
