toolbox functions not working

I have installed and re-installed Matlab 2024b and R2025a on a new desktop PC and each time I get the same error messages upon startup saying:

I've also installed the climate data toolbox and some of the functions are not operating.

I'd appreciate any help.

Answer 1

[Star Strider]

Sometimes this can be due to path problems.

Running these:

restoredefaultpath 
rehash toolboxcache 

from a script or your Command Window may be able to fix it. (These problems can survive a re-install, so it’s worth trying that first.)

If you’re still having problems after that, Contact Support.

I have run the codes. It works. But after restarting the Matlab, the same problem occurs again. What should I do then?

[Walter Roberson]

After the two commands above, either use savepath or use pathtool to save the path.

Answer 2

[Steinar]

If the command:

which -all pathdef

returns several paths, one need to delete (path or file) util one remains.

For me the requierd one was: C:\Program Files\MATLAB\R2024b\toolbox\local\pathdef.m

Then run

restoredefaultpath

rehash toolboxcache
