Question
Hello, I am creating/deleting programmatically some simulink functions recursively, and for debug purpose, I hilghlight blocks I'm currently working on with the hilite_system function, for example: hilite_system(gcbh) I know I can remove the highlighting of a specific block by doing: hilite_system(gcbh,'none') But I don't manage to remove all the highlighting at once. My question is, is there a simple way to do a global "Remove Highlighting" just like Simulink does (without specifying some blocks), or do I have to make a loop and force all my blocks to none one after another? It would work, but it feels like crushing a fly with a cannon. I found the function remove_hilite.p but I don't manage to do what I intend with some random arguments.

There is no single function that can do this. You will need to use a collection of find_system and hilite_system to do this. Example below.
% Get highlighted blocks. Idea is to look for all blocks with yellow background (default highlight color). % This results in a cell array of paths to all blocks that satisfy this condition. % Note that if your highlight color is different or more than one color, you would need to run an % appropriate or multiple commands to get the list of all blocks highlighted no matter what color. hilited_blocks = find_system('my_model','BackgroundColor','yellow') % Pass block list to hilite_system to switch 'off' color. hilite_system(hilited_blocks,'off')
