Hi,

Is it possible there’s a bug in the GSLMinimizer class such that it ignores the step size?

I’m trying a minimization of a function with two parameters:

```
ROOT::Math::Functor f(&function,2);
double step[2] = {1.0,100.0};
double variable[2] = { 1.0,-200.0};
min.SetFunction(f);
min.SetVariable(0,"x",variable[0], step[0]);
min.SetVariable(1,"y",variable[1], step[1]);
```

But the Minization does not work as expected:

(In this table the first column is parameter 1, second column is parameter 2 and third column is the function return value).

We see that the minimizer completely ignores the fact I set the step sizes to a different value, and because of that, it terminates the minization because it cannot converge…

Thank you if someone can confirm this is a bug, or if I’m using this wrong.
