Hello,

How do I convert a cfit object (piecewise polynomial) and export that to standard C code as a function? I want to run the function from a microcontroller.

I am only interested in the value and not the other methods. I have attached the foo.mat which contains the cfit object and the script that I use to call it.

I should have an entry point function somehow with the model?

Edit: Alternatively I can reconstruct the piecewise polynomial model as a function. I would also like to know for future reference, whether I can export other curve fitting algorithm from Matlab into C? Such as Lev-mar (parametric fitting)?

I looked at it further and ended up extracting the breaks and coefs using unmkpp, which are hardcoded in my microcontroller. I converted mkpp and ppval into C. Hopefully this will work well.

I am still wondering about parametric curve fitting in C though.
