Hi.

I am facing problems with fitting the Levy-Tsallis function. I can’t set the power term(-n). Like here…

```
//Function
TF1 *LEVY=new TF1("LEVY","pow((x)*[0]*((([1]-1)*([1]-2))/(([1]*[2])*([1]*[2]+1.019*([1]-2))))*(1+((sqrt(x*x+(1.019*1.019)))-1.019)/([1]*[2])),-n)",0,3);
LEVY->SetParameters(6,100,0.4);
```

This shows it is a zombie function.

Can anybody help me??

Thanks in advance.
