How to use curve fitting in Simulink

Hi everybody,

I'm a beginner in simulink, i'm using it to develop a Fuel Cell model. However, i have some difficulties using Curve Fitting in simulink.

My model draws an I-V curve, and I want to be able to know V at a given I, for any I possible. Fitting the curve after exporting V and I to the workspace using matlab command lines work great, however i am unable to do the fitting in simulink (which would allow me to use the fitting further in m simulation), even with Matlab function bloc.

If anyone has an idea how i could do that, i'd really appreciate any help.

Thanks Jeremy

I am also looking for a way to do exactly this. Let me know if you ever figure it out, and I will do the same!
