Update test suite
Test suite has been updated and solutions rescored. My apologies for the inconvenience.
The test suite is outdated. The lookfor command no longer appears at the See-also section of the help command, and the See-also section of the command which has way more functions than listed in the test suite (MATLAB version R2020a).
The Matlab documentation is improved constantly, so maybe the test cases can be reviewed ;-)
