How can I enable the syntax for a function and the window for the workspace variables?

I was watching one of my colleague using Matlab and I noticed that when he writes a function, on the screen appears the syntax for that function (green arrow in the .jpg file attached), and also the name of the variables in a window (red arrow in the .jpg file attached). How can I enable this feature on my Matlab? Thanks for the help.

See https://www.mathworks.com/help/compiler/mcc.html#d124e20756 for a description of code suggestions.

For this to happen you might need Preferences -> Editor/Debugger -> Automatic Completions -> Suggestions and completions -> Show suggestions automatically

You might also be interested in https://www.mathworks.com/help/matlab/matlab_prog/customize-code-suggestions-and-completions.html which shows how to add code suggestions for functions that you yourself write.

Did you intend to post that first link to a different question? It doesn't seem like it's relevant for this one.

Thanks for your answer but I do not have these options. I would like to remark that I have the 2021a version of Matlab and this may change something..

In R2021a, Preferences -> Keyboard -> MATLAB Keyboard Preferences . Then

• Command WIndow -> Enable function hints
• Editor -> Enable function hints
