I developed a fuzzy model in a Matlab function and like to generate (with the Matlab Coder) a mex function out of it. Furthermore I have a recursive Matlab function, which I also like to have as a mex function.

The Matlab Coder says, that recursive calls are not allowed. I can't figure out how to make C-Code out of my Fuzzy Logic Model either. It seems that Functions like:

   readfis('...')
   evalfis(...)

are not supported, because they are not in the list of supported Matlab Coder functions. But there has to be a way. Is there a workaround for these 2 problems. Cheers, Oliver

You can declare the functions not supported by MATLAB Coder as coder.extrinsic. The extrinsic functions are not compiled by MATLAB Coder, rather they are executed by MATLAB directly... but rest of your code will be compiled into the mex function. Note that extrinsic declarations do not work for non-mex code generation.

I can't work with the extrinsic statement, because I have to translate my fuzzy logic model into C-Code. I want to use it later on independent from Matlab. That is why, I need everything as C-Functions.

My actual question is/was how to do that.

Sorry, as far as I know, nothing in the Fuzzy Logic Toolbox is currently supported for code generation. We would welcome your suggestions for which functions/features should be the highest priority to support, but I do not know when support will be added.
