zcopy(3P)		    Sun Performance Library		     zcopy(3P)

NAME
       zcopy - Copy x to y

SYNOPSIS
       SUBROUTINE ZCOPY(N, X, INCX, Y, INCY)

       DOUBLE COMPLEX X(*), Y(*)
       INTEGER N, INCX, INCY

       SUBROUTINE ZCOPY_64(N, X, INCX, Y, INCY)

       DOUBLE COMPLEX X(*), Y(*)
       INTEGER*8 N, INCX, INCY

   F95 INTERFACE
       SUBROUTINE COPY([N], X, [INCX], Y, [INCY])

       COMPLEX(8), DIMENSION(:) :: X, Y
       INTEGER :: N, INCX, INCY

       SUBROUTINE COPY_64([N], X, [INCX], Y, [INCY])

       COMPLEX(8), DIMENSION(:) :: X, Y
       INTEGER(8) :: N, INCX, INCY

   C INTERFACE
       #include <sunperf.h>

       void  zcopy(int	n,  doublecomplex  *x, int incx, doublecomplex *y, int
		 incy);

       void zcopy_64(long n, doublecomplex *x, long  incx,  doublecomplex  *y,
		 long incy);

PURPOSE
       zcopy Copy x to 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)
		 of  DIMENSION at least ( 1 + ( n - 1 )*abs( INCX ) ).	Before
		 entry, the incremented array X must  contain  the  vector  x.
		 Unchanged on exit.

       INCX (input)
		 On entry, INCX specifies the increment for the elements of X.
		 Unchanged on exit.

       Y (output)
		 of DIMENSION at least ( 1 + ( n - 1  )*abs(  INCY  )  ).   On
		 entry,	 the incremented array Y must contain the vector y. On
		 exit, Y is overwritten by the vector x.

       INCY (input)
		 On entry, INCY specifies the increment for the elements of Y.
		 Unchanged on exit.
