Hello,

I'm trying to use the MATLAB Coder app to convert a series of functions to C/C++ functions.

I create a structure, and some elements of that structure are functions, like in the image below (the image represents a silly example with no meaning).

However, the converter fails because of the function handle:

"Function output 'model' cannot be a structure containing a function handle".

Anyone knows if I'm doing something wrong or there's a workaround it? I do need functions within a structure.

Machine: Mac,

Version: Matlab 2017b

Any help is appreciated.

Thanks

Function handles, and values containing them, are not supported as inputs and outputs from entry-point functions. As a workaround could move testFun to a separate file on the path, return the name, and use str2func when back in MATLAB.

If you describe what you're trying to achieve with this struct, there may be a better workaround.

Thank you Ryan for the fast answer.

What i'm trying to do is to build a structure (model) with the several function handles I need in the main code, and pass "model" to all functions that need the function handles.

I made it this way to avoid having many many files, one for each function handle.

but I think your workaround may work.
