The easiest way is to restart MATLAB. During startup, MATLAB will automatically regenerate the support package paths under the root folder returned by 'matlabshared.supportpkg.getSupportPackageRoot' and add them to the MATLAB path.
However, if you want to restore the support packages paths for the current MATLAB session, you can reset the support package root as follows:
>> a = matlabshared.supportpkg.getSupportPackageRoot();
>> matlabshared.supportpkg.setSupportPackageRoot(a)
The 'setSupportPackageRoot' function will automatically run 'savepath' to save the path for future MATLAB sessions. You may need to have administrative privileges to run this function.
