subroutine zdrot (integerN, complex*16, dimension( * )CX, integerINCX, complex*16, dimension( * )CY, integerINCY, double precisionC, double precisionS)

ZDROT Purpose:

Applies a plane rotation, where the cos and sin (c and s) are real
and the vectors cx and cy are complex.

Parameters:

N

N is INTEGER
 On entry, N specifies the order of the vectors cx and cy.
 N must be at least zero.

CX

CX is COMPLEX*16 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

INCX is INTEGER
 On entry, INCX specifies the increment for the elements of
 CX. INCX must not be zero.

CY

CY is COMPLEX*16 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

INCY is INTEGER
 On entry, INCY specifies the increment for the elements of
 CY. INCY must not be zero.

C

C is DOUBLE PRECISION
 On entry, C specifies the cosine, cos.

S

S is DOUBLE PRECISION
 On entry, S specifies the sine, sin.
