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

zcopy 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 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. INCX must not be zero. Unchanged on exit.
-
* Y (input/output)
-
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 (input)
-
On entry, INCY specifies the increment for the elements of Y. INCY must not be zero. Unchanged on exit.
