void dcopy(int n, double *x, int incx, double *y, int incy);
void dcopy_64(long n, double *x, long incx, double *y, long
incy);
dcopy Copy x to y where x and y are n-vectors.
N (input)
On entry, N specifies the number of elements in
the vector. N must be at least one for the sub-
routine 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.
