SYNOPSIS
SUBROUTINE SCOPY(N, X, INCX, Y, INCY)
INTEGER N, INCX, INCY
REAL X(*), Y(*)
SUBROUTINE SCOPY_64(N, X, INCX, Y, INCY)
INTEGER*8 N, INCX, INCY
REAL X(*), Y(*)
F95 INTERFACE
SUBROUTINE COPY([N], X, [INCX], Y, [INCY])
INTEGER :: N, INCX, INCY
REAL, DIMENSION(:) :: X, Y
SUBROUTINE COPY_64([N], X, [INCX], Y, [INCY])
INTEGER(8) :: N, INCX, INCY
REAL, DIMENSION(:) :: X, Y
C INTERFACE
#include <sunperf.h>
void scopy(int n, float *x, int incx, float *y, int incy);
void scopy_64(long n, float *x, long incx, float *y, long incy);
PURPOSEscopy 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)
( 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)
( 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.
