## SYNOPSIS

### Functions/Subroutines

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

## Function/Subroutine Documentation

### subroutine CSROT (integerN, complex, dimension( * )CX, integerINCX, complex, dimension( * )CY, integerINCY, realC, realS)

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. jack dongarra, linpack, 3/11/78.`

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.`
