Parameters

side  MatrixOperationSide

            = 'L': apply Q or QH from the Left;
            = 'R': apply Q or QH from the Right.
            

trans  TransposeOperation

            = 'N':  No transpose, apply Q;
            = 'C':  Conjugate transpose, apply QH.
            

m  Int32

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

n  Int32

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

k  Int32

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

a  Span<Complex<Single>>

            A is TComplex array, dimension (LDA,K)
            The i-th column must contain the vector which defines the
            elementary reflector H(i), for i = 1,2,...,k, as returned by
            ZGEQRF in the first k columns of its array argument A.
            

lda  Int32

            The leading dimension of the array A.
            If SIDE = 'L', LDA >= max(1,M);
            if SIDE = 'R', LDA >= max(1,N).
            

tau  ReadOnlySpan<Complex<Single>>

            TAU is TComplex array, dimension (K)
            TAU(i) must contain the scalar factor of the elementary
            reflector H(i), as returned by ZGEQRF.
            

c  Span<Complex<Single>>

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

ldc  Int32

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

info  Int32

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

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