- you are inside a function
- you assign to a variable named eval
- you run a script
- the script clears the variable named eval
- after the script you try to use eval
What happened to eval function?

I am using R2022a, and the eval function is giving me an error,
eval(['4 + 5'])
Unrecognized function or variable 'eval'.
Ignore "ans = 9" in my question, since that's what happened when I ran it online in R2022a; that is the expected behavior but not what I'm getting on my computer.
Any idea what's going on? I tried restarting Matlab and the error persisted.

I think maybe you could get this error under the odd conditions:
I am not positive this will generate that exact error, but MATLAB is allowed to lose track of functions and variables if you do this or you assign to a name inside the script when the name matches a function name
