Hello Alo,

It looks like there is some issue with your guidefunc.m file.

Here are few things you can try to fix this.

• If the file has been modified, restore it to its original state. You can do this by reinstalling MATLAB or by restoring the file from a backup if you have one.
• try to upgrade matlab to a newer version.
• If the issue persists, consider reinstalling the GUIDE components. This can be done through the MATLAB installer by selecting the "Add-Ons" or "Modify" option, depending on your MATLAB version.
• Make sure your MATLAB path is set correctly. Sometimes, custom paths can interfere with built-in functions. Use the restoredefaultpath command to reset your path to the default and see if that resolves the issue:

restoredefaultpath;
rehash toolboxcache;
savepath;

• If none of the above steps work, consider reaching out to MathWorks support. They can provide more detailed assistance and might have additional insights based on your specific MATLAB version and setup.

I hope it helps!
