MATLAB Coder Onramp Issue - Section 4 Call C Code from MATLAB

Hi all,

I am currently running through some of the learning materails online for both MATLAB and Simulink. I have started going over the MATLAB Coder Onramp which goes through the mecanisms for generating C code from MATLAB. This is using the website based version of the courses and as such the MATLAB environement is within the web browser itself.

However, I seem to be stuck at section 4 "Call C Code From MATLAB - Verify Generated Code". The task asks the following,

To generate a MEX function, you don't need to specify a configuration because the codegen function generates MEX by default.

codegen fcn -args {var} -report

If your function has input arguments and you want a code generation report, you can continue using ‑args and ‑report.

Task

Generate MEX code for the detectpH function. Use I2 as the example input.

The code may take up to ten seconds to generate.

Now I have added my result and compared this to the "See Solution" and it is the same

codegen detectpH -args {I2} -report

However, when I select Submit, I get an error using Codegen. I have cleared my entry, closed and reopened the course and even copied and pasted the result from the "See Solution" too to make sure there were no spelling mistakes but still no luck.

I am wondering if this is an issue to do with the in browser environment perhaps?

I did have issues with generating the C code earlier in the course, but as the training allowed me to continune, I assumed this was going to be dealt with in the next sections.

Hopefully I am doing something daft and its a simple fix.

I have attached the Build Log for additional infromation.

Thanks,

Jason

I can duplicate. I'll report this internally.

I got the same problem.
