NAME

scopy - Copy x to y

SYNOPSIS

SUBROUTINE SCOPY (N, X, INCY, Y, INCY )

INTEGER INCX, INCY, N

REAL    X( ∗ ), Y( ∗ )

#include <sunperf.h>

void scopy(int n, float ∗sx, int incx, float ∗sy, int incy) ;

PURPOSE

SCOPY - Copy x to y where x and y are n-vectors. 
 

PARAMETERS

N - INTEGER. 
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 - REAL             array of DIMENSION at least
( 1 + ( n - 1 )∗abs( INCX ) ). Before entry, the incremented array X must contain the vector x. Unchanged on exit.

INCX - INTEGER. 
On entry, INCX specifies the increment for the elements of X.  INCX must not be zero. Unchanged on exit.

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

INCY - INTEGER. 
On entry, INCY specifies the increment for the elements of Y.  INCY must not be zero. Unchanged on exit.
