Parameters

side  MatrixOperationSide

C# Copy

SIDE is CHARACTER*1
= 'L': apply Q or Q**H from the Left;
= 'R': apply Q or Q**H from the Right.

trans  TransposeOperation

C# Copy

TRANS is CHARACTER*1
= 'N':  No transpose, apply Q;
= 'C':  Transpose, apply Q**H.

m  Int32

C# Copy

M is INTEGER
The number of rows of the matrix C. M >= 0.

n  Int32

C# Copy

N is INTEGER
The number of columns of the matrix C. N >= 0.

k  Int32

C# Copy

K is INTEGER
The number of elementary reflectors whose product defines
the matrix Q.
If SIDE = 'L', M >= K >= 0;
if SIDE = 'R', N >= K >= 0.

a  Array2D<TComplex>

C# Copy

A is COMPLEX*16 array, dimension
                     (LDA,M) if SIDE = 'L',
                     (LDA,N) if SIDE = 'R'
The i-th row must contain the vector which defines the
elementary reflector H(i), for i = 1,2,...,k, as returned by
ZGERQF in the last k rows of its array argument A.

C# Copy

LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,K).

tau  Array1D<TComplex>

C# Copy

TAU is COMPLEX*16 array, dimension (K)
TAU(i) must contain the scalar factor of the elementary
reflector H(i), as returned by ZGERQF.

c  Array2D<TComplex>

C# Copy

C is COMPLEX*16 array, dimension (LDC,N)
On entry, the M-by-N matrix C.
On exit, C is overwritten by Q*C or Q**H*C or C*Q**H or C*Q.

C# Copy

LDC is INTEGER
The leading dimension of the array C. LDC >= max(1,M).

info  Int32

C# Copy

INFO is INTEGER
= 0:  successful exit
< 0:  if INFO = -i, the i-th argument had an illegal value

. . H(k)**H
as returned by ZGERQF. Q is of order M if SIDE = 'L' and of order N
if SIDE = 'R'.
