The error is most likely the result of an old classpath.txt file from a previous release. Try the following to resolve the error:
1. In the MATLAB Command Window, type:
which -all classpath.txt
2. This should return $MATLAB/toolbox/local/classpath.txt, where $MATLAB is the directory in which MATLAB was installed. If MATLAB returns something else, remove the classpath.txt file.
If which -all classpath.txt returns nothing, reinstall MATLAB.
NOTE: DO NOT remove the classpath.txt file that is located in the $MATLAB/toolbox/local directory as this is required by MATLAB. If you accidentally remove this file, reinstall MATLAB.
