Error Matlab 2022 and 2023 : Undefined function 'find' for input arguments of type 'pattern'

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?

[Rik]

What does the command below return?

which find -all

anyway, thank you Rik for the response

[Dyuman Joshi]

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:

Hello everyone,

I thought my problem is solved after following the answer by Prashanth Soundararajan on this thread:

https://www.mathworks.com/matlabcentral/answers/1462924-why-do-i-receive-an-error-stating-that-my-uiaxes-component-cannot-be-added

It's simply related to path issues, so it's simply solved by:

Try restoring the default path by typing the following in the MATLAB Command Window:

>>restoredefaultpath

>>rehash toolboxcache

>>savepath
