dcopy() void dcopy ( int  n, double  x[], int  incx, double  y[], int  incy  ) y <- x (BLAS 1) Purpose This routine copies a vector x to a vector y. Parameters [in] n Number of elements in vectors x and y. (If n <= 0, returns without computation) [in] x[] Array x[lx] (lx >= 1 + (n - 1)*abs(incx)) Input vector x. [in] incx Storage spacing between elements of x. [out] y[] Array y[ly] (ly >= 1 + (n - 1)*abs(incy)) Output vector y. (To be overwritten by x) [in] incy Storage spacing between elements of y.
