Alternatives for functions not supported for code generation

Hi All,
I am using MATLAB coder to generate C code from MATLAB code files.
Some functions are not supported for code generations
Suggestions on alternate options for the above-mentioned functions would be of great help.

The following are supported for code generation in R2023b:
Still not supported:
  • dir
  • incidence
dir() is a tricky one, as MATLAB Coder is designed to be able to target systems that do not have file systems.
incidence is something that could be programmed yourself with (for example) accumarray (if a "full" matrix is acceptable) or using sparse if you need a sparse version.
I would suggest to you that it would be easier if you were to upgrade to R2023b. Otherwise you are going to need to call coder.ceval

If I may ask one more question,
I'm generating the C++ code using MATLAB coder to use the generated code in OpenCL. I would like to ask for your suggestions for understanding if this is the right way forward : i.e. MATLAB > C++ > OpenCL.
I came across a package such as MatCL ( ). But since the interface is not maintained and not well documented, I wasn't sure if I can use that.
