Parameters

n Int32

            number of elements in input vector(s)

x Span<Double>

            Dimension N
            T precision vector with N elements

incx Int32

            storage spacing between elements of DX

y Span<Double>

            Dimension N
            T precision vector with N elements

incy Int32

            storage spacing between elements of DY

param Double[]

Remarks

            THE ELEMENTS OF DX ARE IN
               (DY^T)
               DX(LX+I*INCX), I = 0 TO N-1, WHERE LX = 1 IF INCX  >=  0, ELSE
               LX = (-INCX)*N, AND SIMILARLY FOR SY USING LY AND INCY.
               WITH DPARAM(1)=DFLAG, H HAS ONE OF THE FOLLOWING FORMS.
               DFLAG=-1.D0     DFLAG=0.D0        DFLAG=1.D0     DFLAG=-2.D0
                 (DH11  DH12)    (1.D0  DH12)    (DH11  1.D0)    (1.D0  0.D0)
               H=(          )    (          )    (          )    (          )
                 (DH21  DH22),   (DH21  1.D0),   (-1.D0 DH22),   (0.D0  1.D0).
