Why do I get:"Undefined function or variable 'pathtool'."

I moved from 2015b to 2017b and at startup a lot of directories in the path are not recognized. Some of them I did not even know I had in the path :

/Applications/MATLAB_R2017b.app/toolbox/matlab/external/engines/python Warning: Name is nonexistent or not a directory:

I guess the default matlab home directory is no longer in /Users/mysuername/Documents/matlab. When I try to fix this by clicking on 'Set Path' in the 'HOME' tab of the main Matlab window the response is and error message "Undefined function or variable 'pathtool'."

Something went wrong. If even the built-in pathtool cannot be found, the installation of R2017b failed. A re-installation is the first idea. The command restoredefaultpath might help also, but this should run after the installation already.

Thanks, restoredefaultpath did the trick. I then only had to add my ....Documents/matlab with subfolders to the path
