I have a Simulink model that has an s-function that is locked so I do not have the build files for that function. It is from a third party and I just need to use it for simulation. It is working in my current Simulink model. I only have a .mexw64 file for the function.
Is it possible to still export this with Simulink coder to my own C or C++ external file.
I eventually want to run these blocks in Python.
Please let me know if you have any insight of if this is possible. I am currently getting a BuildInfo.mat error which I don't have.
Thank you so much for any help.

It depends on how the s-function was built. If the s-function was built as an "inlined" s-function, then a TLC file is required to generate code, otherwise a TLC file is not required. If a TLC is required, you will get an error message when you try to generate C/C++ code for a model that contains the s-functionn block indicating that the TLC file is missing.
