PLASMA_dormqr - Overwrites the general complex M-by-N matrix C with

            SIDE = 'L'     SIDE = 'R'

TRANS = 'N': Q * C C * Q TRANS = 'C': Q**T * C C * Q**T

where Q is a complex unitary matrix defined as the product of k elementary reflectors

  Q = H(1) H(2) . . . H(k)

as returned by PLASMA_dgeqrf. Q is of order M if SIDE = PlasmaLeft and of order N if SIDE = PlasmaRight.

Parameters
[in]sideIntended usage: = PlasmaLeft: apply Q or Q**T from the left; = PlasmaRight: apply Q or Q**T from the right.
[in]transIntended usage: = PlasmaNoTrans: no transpose, apply Q; = PlasmaTrans: ugate transpose, apply Q**T.
[in]MThe number of rows of the matrix C. M >= 0.
[in]NThe number of columns of the matrix C. N >= 0.
[in]KThe number of elementary reflectors whose product defines the matrix Q. If side == PlasmaLeft, M >= K >= 0. If side == PlasmaRight, N >= K >= 0.
[in]ADetails of the QR factorization of the original matrix A as returned by PLASMA_dgeqrf.
[in]LDAThe leading dimension of the array A. If side == PlasmaLeft, LDA >= max(1,M). If side == PlasmaRight, LDA >= max(1,N).
[in]descTAuxiliary factorization data, computed by PLASMA_dgeqrf.
[in,out]COn entry, the M-by-N matrix C. On exit, C is overwritten by Q*C or Q**T*C.
[in]LDCThe leading dimension of the array C. LDC >= max(1,M).
