Hello,

I found this kind of error recently on my matlab 2022a, 2022b, and even 2023 : Undefined function 'find' for input arguments of type 'pattern'. Before (1-2 months ago) they worked fine. Anyone know this issue?

Please copy and paste the whole error message i.e. all of the red text.

Also, post the code where you use the function find() and it gives the error.

FYI, 2 months ago there was no problem. I don't think it's my script failure. Now, even I can't add any single component (axes, button etc) in app designer, and got this message:
