subroutine csrot (N, CX, INCX, CY, INCY, C, S)
subroutine csrot (integerN, complex, dimension( * )CX, integerINCX, complex, dimension( * )CY, integerINCY, realC, realS)
CSROT applies a plane rotation, where the cos and sin (c and s) are real and the vectors cx and cy are complex. jack dongarra, linpack, 3/11/78.
N is INTEGER On entry, N specifies the order of the vectors cx and cy. N must be at least zero.
CX is COMPLEX array, dimension at least ( 1 + ( N - 1 )*abs( INCX ) ). Before entry, the incremented array CX must contain the n element vector cx. On exit, CX is overwritten by the updated vector cx.
INCX is INTEGER On entry, INCX specifies the increment for the elements of CX. INCX must not be zero.
CY is COMPLEX array, dimension at least ( 1 + ( N - 1 )*abs( INCY ) ). Before entry, the incremented array CY must contain the n element vector cy. On exit, CY is overwritten by the updated vector cy.
INCY is INTEGER On entry, INCY specifies the increment for the elements of CY. INCY must not be zero.
C is REAL On entry, C specifies the cosine, cos.
S is REAL On entry, S specifies the sine, sin.
