Matlab coder euclidean example fail in 2023a update 3 - workaround?

The coder euclidean example from

https://www.mathworks.com/help/coder/gs/generating-c-code-from-matlab-code-using-the-matlab-coder-project-interface.html

fails at the "check for run-time issues" stage (after clicking "check for issues") at

idx = ones(1,2);

with

"Overloading the method 'subsindex' is not supported for code generation."

Does anyone know a workaround?

I can't reproduce in R2023a on Windows 11 using the MinGW-w64 C/C++ compiler.

Hi Adam,

I understand that you're encountering errors while attempting to generate the code for the MATLAB coder Euclidean example, despite following the documented workflow.

Like Cris LaPierre mentioned in the comments, I also couldn't replicate the error on MATLAB R2023a version. However, I do have a workaround that might help you.

You can try replacing the code that initializes the idx and distance variables with the following code:

idx = [1,1]; 
distance = [norm(x-cb(:,1)), norm(x-cb(:,1))]; 

I hope this solution works for you. If not, there might be an issue with the C compiler you have installed. In that case, consider reinstalling the compilers.

Hope this Helps!

Best regards,

Poorna.
