PLASMA_sormlq - 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_sgeqrf. Q is of order M if SIDE = PlasmaLeft and of order N if SIDE = PlasmaRight.
[in] | side | Intended usage: = PlasmaLeft: apply Q or Q**T from the left; = PlasmaRight: apply Q or Q**T from the right. |
[in] | trans | Intended usage: = PlasmaNoTrans: no transpose, apply Q; = PlasmaTrans: ugate transpose, apply Q**T. |
[in] | M | The number of rows of the matrix C. M >= 0. |
[in] | N | The number of columns of the matrix C. N >= 0. |
[in] | K | The number of rows of elementary tile reflectors whose product defines the matrix Q. If side == PlasmaLeft, M >= K >= 0. If side == PlasmaRight, N >= K >= 0. |
[in] | A | Details of the LQ factorization of the original matrix A as returned by PLASMA_sgelqf. |
[in] | LDA | The leading dimension of the array A. LDA >= max(1,K). |
[in] | descT | Auxiliary factorization data, computed by PLASMA_sgelqf. |
[in,out] | C | On entry, the M-by-N matrix C. On exit, C is overwritten by Q*C or Q**T*C. |
[in] | LDC | The leading dimension of the array C. LDC >= max(1,M). |
PLASMA_SUCCESS | successful exit |
<0 | if -i, the i-th argument had an illegal value |
