Occasionally when creating a SimFunction, SimBiology returns a failure to compile error, what causes this?

Sometimes when I try to create and compile a SimFunction, the following error happens:

Unable to create SimFunction:

--> Error reported from ODE Compilation:

Not enough input arguments.

Caused by:

Error using SimBiology.internal.compile

--> Error reported from ODE Compilation:

Not enough input arguments.

The code file will run in other versions of MATLAB (e.g. I just got this error in R2023a, but it runs fine on R2022b).

Hi Craig,

My guess is that this is some sort of bug. But it's hard to say definitively without reproduction steps. If you can consistently reproduce this, can you share the code? I'm assuming you don't want to share it publicly here on MATLAB Answers, so feel free to contact me directly. In general, I encourage folks to report anything that feels like a bug to Technical Support.
