### Fitting curve custom function

Posted:

**Tue Apr 13, 2021 12:45 pm**Hello all,

I'm not a poweruser of SDL component and not the best math whiz.

My problem is that I have some data point and I want to fit them to a custom function Y(x)= (B * x^n )

Is there a way to find the parameters B and n?

I need to fit this function, because splines don't match enough to my requierement.

In fact, it's the king's law for hot wire calibration: E = A + B* x^n.

Where A is the offset @X = 0. I have the param A.

I need to find the B and n.

Best regards

Lionel
