PLASMA_zungqr - 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_zgeqrf.

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_zgeqrf.
[in] LDA The leading dimension of the array A. LDA >= max(1,M).
[in] T Auxiliary factorization data, computed by PLASMA_zgeqrf.
[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
