How to generate the custom help box for a custom function (More Help...)

41 views (last 30 days)
Hi everyone,
I recently dealt with proper help for my custom functions.
I found out that there are 4 points one can handle:
  1. doc myfun: Will show file help or if available the html help (https://de.mathworks.com/help/matlab/matlab_prog/display-custom-documentation.html)
  2. writing your function, then typing in the opening bracket and waiting. A small box will appear showing input parameters
  3. help myfun: Will display the comments at the top of the function (https://de.mathworks.com/help/matlab/matlab_prog/add-help-for-your-program.html)
  4. tab completion with functionSignatures.json (https://de.mathworks.com/help/matlab/matlab_prog/customize-code-suggestions-and-completions.html and also https://undocumentedmatlab.com/articles/user-defined-tab-completions-take-2)
For 2.: Where can I find how to do this? For custom functions, only the input parameters are shown. But for Matlab Built-Ins, all available syntaxes are shown. They sometimes even differ from the "syntax" part in the html help, see movmean function help and the "bracket opening"-help for the info on datetime object, see picture below.
Are there even other "standard" help functionalities besides the four above?

Hi there,
this question you linked does not seem to be answered at all. From what I understood, this refers to point 4 I mentioned and is only referring to live scripts, not the command window? See Jan's comment.

I encountered the same issue.
Is there a solution (for the normal editor, not the live-script editor) ?

I bet the normal editor shall be replaced soon, no updates were made a long time and all efforts were spent to the javascript/online interface.
