SYNOPSIS
subroutine zdrot( n, zx, incx, zy, incy, c, s )
.. Scalar Arguments .. integer,intent(in) :: incx, incy, n double precision,intent(in) :: c, s .. .. Array Arguments .. complex(kind=real64),intent(inout) :: zx( * ), zy( * ) ..
DEFINITION
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.
OPTIONS
N
N is INTEGER On entry, N specifies the order of the vectors cx and cy. N must be at least zero.
ZX
ZX is complex(kind=real64) array, dimension at least ( 1 + ( N - 1 )*abs( INCX ) ). Before entry, the incremented array ZX must contain the n element vector cx. On exit, ZX is overwritten by the updated vector cx.
INCX
INCX is INTEGER On entry, INCX specifies the increment for the elements of ZX. INCX must not be zero.
ZY
ZY is complex(kind=real64) array, dimension at least ( 1 + ( N - 1 )*abs( INCY ) ). Before entry, the incremented array ZY must contain the n element vector cy. On exit, ZY is overwritten by the updated vector cy.
INCY
INCY is INTEGER On entry, INCY specifies the increment for the elements of ZY. 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.
