Function SCRATON problem

[Zbigniew Jachimowicz]

I have a problem with the SCRATON function. Is it possible to use a different function in the SCRATON function set (f, x, y, xe, eps, hmin), eg f (x, y)? If so, what should be declared outside and inside the SCRATON and f (x, y) function

I complement the previous post with the SCRATON function and f (x, y)
