SYNOPSIS


 

Functions/Subroutines


subroutine csrot (N, CX, INCX, CY, INCY, C, S)
CSROT  

Function/Subroutine Documentation

 

subroutine csrot (integer N, complex, dimension( * ) CX, integer INCX, complex, dimension( * ) CY, integer INCY, real C, real S)

CSROT

Purpose:

 CSROT 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 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 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 REAL
           On entry, C specifies the cosine, cos.


S

          S is REAL
           On entry, S specifies the sine, sin.
