Hi, I'm trying to import some C++ controller code I have written to test it with my simulink plant before putting it on hardware. I'm following this tutorial:
https://au.mathworks.com/help/releases/R2025b/simulink/ug/import-custom-code-using-the-simulink-code-importer-wizard.html?searchHighlight=Code+Importer+wizard&s_tid=doc_srchtitle
When I get to the "Analyze" stage it throws this error:
Error:Failed to parse custom code.
Caused by:
"/Users/alfieeagleton/Desktop/Uni/Thesis/Matlab/cpp/include/actuator.hpp", line 23: error: cannot open source file "cmath"
| #include
| ^
I have included <cmath> and <algorithm> and it will throw an error on both if I remove <cmath>.
Does anyone know what I'm doing wrong?
Thanks
