breakpoints grey and cannot be set

i cannot use breakpoints...all in grey color

With the view you happened to show, we cannot be sure that you have clicked on a particular line.

What happens if you left click on the '-' that is before the line you want to set the breakpoint at?

The editor shows warnings/errors with the red flag at the top -- breakpoints can't be set if there are compilation errors.

Fix those and I'll bet joy will ensue...

To me the colors look orange, which is warning like no semi-colon on the line. Red can prevent breakpoints but I only see orange.

Hello,

Ideally you should be able to set breakpoints using the left click on "-" symbol beside the line number, if somehow that is not possible you can try using dbstop and see if you can set a breakpoint. Additionally refer to this document to understand debugging in MATLAB Editor.

Sometimes if the GUI is not saved the color is grey, after you have saved click on "-" and it began coloured. I hope it will be useful to other users as well.
