Hi there,
I'm running on a Mac (Sonoma, M1 Chip) with Matlab 2024a, and I'm having problems with the inversion tutorial, too, starting at step 3. Here's what comes up when I execute it in the Matlab GUI:

The same error pops up when I run this step from the command line:

But I'm sure I installed m1qn3. Here are the contents of the m1qn3 folder

and the m1qn3 install folder

Any ideas on what might be causing these errors?
Thanks!
Anna
