NAME    [Toc]    [Back]

     dswap, sswap, zswap, cswap	- BLAS level ONE swap subroutines


FORTRAN	77 SYNOPSIS
     subroutine	dswap( n, dx, incx, dy,	incy )
     integer	       incx, incy, n
     double precision  dx( 1 ),	dy( 1 )

     subroutine	sswap( n, sx, incx, sy,	incy )
     integer	       incx, incy, n
     real	       sx( 1 ),	sy( 1 )

     subroutine	zswap( n, zx, incx, zy,	incy )
     integer	       incx, incy, n
     complex*16	       zx( 1 ),	zy( 1 )

     subroutine	cswap( n, cx, incx, cy,	incy )
     integer	       incx, incy, n
     complex	       cx( 1 ),	cy( 1 )

C SYNOPSIS    [Toc]    [Back]

     void dswap( n, zx,	incx, zy, incy )
     Integer	       incx, incy, n
     double	       (*dx)[ n	], (*dy)[ n ];

     void sswap( n, zx,	incx, zy, incy )
     Integer	       incx, incy, n
     float	       (*sx)[ n	], (*sy)[ n ];

     void zswap( n, zx,	incx, zy, incy )
     Integer	       incx, incy, n
     Zomplex	       (*zx)[ n	], (*zy)[ n ];

     void cswap( n, cx,	incx, cy, incy )
     Integer	       incx, incy, n
     Complex	       (*cx)[ n	], (*cy)[ n ];

DESCRIPTION    [Toc]    [Back]

     dswap, sswap, zswap and cswap interchange n values	of vector x and	vector
     y.	 incx and incy specify the increment between two consecutive elements
     of	respectively vector x and y.
