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);
PURPOSEzcopy 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.
