MATLAB giving me an error code suddenly?

So, I edited a code that had previously been running perfectly and I started getting a ton of error codes. So, I went back the original code and ran it and continued to get error codes. I have no idea why this is happening and I've already tried closing MATLAB and re-opening it. I would post my code, but its sensitive material. How do I, like, reset it or something?

Looks like

• Your "new original" code isn't really quite the original, working version, or
• there could be data-dependent errors (have you duplicated a previous case exactly?)

There's nothing anybody here can do for you except remind of the importance of working backups before committing to large changes if you can't at least show enough of the offending code that can see what errors are.

Yes, reset it by recalling it from your backup/archive. If you don't have that and haven't exited MATLAB, hit the undo arrow until you can't anymore. Otherwise you're out of luck. You can hire Mathworks consulting and have them sign a Confidential Disclosure Agreement with you if you need to.

Some other possibilities:

• some MATLAB files have become corrupted, e.g. accidently overwritten or edited.
• a change to the MATLAB path has changed which functions are available, or which ones are being run.
• the toolbox cache is out of date.
• the license for some toolbox is no longer available.

Without knowing the exact error messages it is impossible to know what is going on.
