[SciPy-user] NewBie: Fit Data to an implicit function

[Niklas Papathanasiou]

Hi!

I like to fit data to an implicit function.
I(U)=I0*exp((U-I*Rs)/(A*k*T)-1)+(U-IRs)/Rp
I,U are data
I0,Rs,Rp,A are Parameter
k,T are physical constants

Did anyone did this before or do I have to start from the scratch?

Many thanks for any help

yours
Beeble
