cswap(3P) Sun Performance Library cswap(3P)NAMEcswap - Exchange vectors x and y.
SYNOPSIS
SUBROUTINE CSWAP(N, X, INCX, Y, INCY)
COMPLEX X(*), Y(*)
INTEGER N, INCX, INCY
SUBROUTINE CSWAP_64(N, X, INCX, Y, INCY)
COMPLEX X(*), Y(*)
INTEGER*8 N, INCX, INCY
F95 INTERFACE
SUBROUTINE SWAP([N], X, [INCX], Y, [INCY])
COMPLEX, DIMENSION(:) :: X, Y
INTEGER :: N, INCX, INCY
SUBROUTINE SWAP_64([N], X, [INCX], Y, [INCY])
COMPLEX, DIMENSION(:) :: X, Y
INTEGER(8) :: N, INCX, INCY
C INTERFACE
#include <sunperf.h>
void cswap(int n, complex *x, int incx, complex *y, int incy);
void cswap_64(long n, complex *x, long incx, complex *y, long incy);
PURPOSEcswap Exchange x and y where x and y are n-vectors.
ARGUMENTS
N (input)
On entry, N specifies the number of elements in the vector.
N must be at least one for the subroutine to have any visible
effect. Unchanged on exit.
X (input/output)
( 1 + ( n - 1 )*abs( INCX ) ). On entry, the incremented
array X must contain the vector x. On exit, the y vector.
INCX (input)
On entry, INCX specifies the increment for the elements of X.
Unchanged on exit.
Y (input/output)
( 1 + ( n - 1 )*abs( INCY ) ). On entry, the incremented
array Y must contain the vector y. On exit, the x vector.
INCY (input)
On entry, INCY specifies the increment for the elements of Y.
Unchanged on exit.
