Unable to compile on Apple M1

First of all, thanks for this package – it helps my student write a bit to compare his Julia code to some Matlab code.

Just that on my machine I am not able to compile, the error message is

So I am amazed that it finds Matlab automatically (cool!) but maybe it does not like that 2023b is arm64? Just for completeness, I am not in Rosetta2 mode so I am

Same thing happens to me. Is there an update to this? Thanks.

This is the same as Issue #205

Since it started earlier, let's continue there.

Yes, let‘s close this, I must have missed the other one.
