In Matlab 2020, you have to use ctrl+/ (cmd+/ for mac) to comment a block and to uncomment you have to use ctrl+t (cmd+t for mac).

Ctrl + R comment selected lines. Ctrl + T uncomment select lines.

Simply start with *... and write whatever you want. This will enable you to write a very long comment line
For example *... This is a very very long comment
Rather than comment large sections of code, I bypass them with the following syntax.
for dont_go_here = 
% code I want to skip including all nested comments, etc. can stay here unmolested
This assumes that your if, for, case, try, and switch commands within that block are all terminated properly with an 'end' Otherwise the script won't parse.
