SYNOPSIS
Functions/Subroutines subroutine zrot (N, CX, INCX, CY, INCY, C, S) ZROT Function/Subroutine Documentation subroutine zrot (integerN, complex*16, dimension( * )CX, integerINCX, complex*16, dimension( * )CY, integerINCY, double precisionC, complex*16S) ZROT Purpose: ZROT applies a plane rotation, where the cos (C) is real and the sin (S) is complex, and the vectors CX and CY are complex. Parameters: N N is INTEGER The number of elements in the vectors CX and CY. CX CX is COMPLEX*16 array, dimension (N) On input, the vector X. On output, CX is overwritten with C*X + S*Y. INCX INCX is INTEGER The increment between successive values of CY. INCX <> 0. CY CY is COMPLEX*16 array, dimension (N) On input, the vector Y. On output, CY is overwritten with -CONJG(S)*X + C*Y. INCY INCY is INTEGER The increment between successive values of CY. INCX <> 0. C C is DOUBLE PRECISION S S is COMPLEX*16 C and S define a rotation [ C S ] [ -conjg(S) C ] where C*C + S*CONJG(S) = 1.0.
