I want matlab to issue a warning, with a lot of details. However, i don't want to flood the command propmt. i thought of issuing the warning and then adding an (ofline) link to the relevant documentation. I mean that the user can click on the command prompt and then get to the relevant section. how would I do this?
many thanks

You can use links in such messages, but I'm not sure if you can taget a specific section of a doc page. That might also be subject to change without warning over several releases.
