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.
