Unable to run the 'restoredefaultpath' function

When trying to run the 'restoredefaultpath' command in the MATLAB Command Window, the following error message is printed:

"Unable to run the 'restoredefaultpath' function, because it is not supported for this product offering."

In addition, there are several warning messages printed in the MATLAB Command Window upon startup, all along the lines of:

"Warning: Function <function name> has the same name as a MATLAB builtin. We suggest you rename the function to avoid a potential name conflict."

How do I resolve these errors?

This error is likely because the path to the MATLAB installation is corrupted. This may have occurred due to multiple MATLAB installations with folders migrated from another MATLAB installation using 'addpath' and 'savepath'.

The following are some potential workarounds:

1. Check the MATLAB installation location and the contents of 'toolbox\local\pathdef.m' and see if there are entries from another MATLAB installation. If so, manually remove these entries and try restarting MATLAB.
2. Rename the current MATLAB folder to a different name (for example, 'MATLAB_old'). Then restart MATLAB. This should create a new MATLAB folder.
3. Re-install MATLAB.
