## 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.
