MATLAB: How to get a unconnected line handle that branching from a normally connected line

handlejunctionsimulinkunconnected line

After deleting the All scope block in the Simulink model programmatically, I tried to delete All the line connected to the scope too, but there is a problem that the line connected normally is also deleted. I want to delete only the unconnected lines that are branched from the normal line. How do I do this?

ScopeBlks=find_system(gcs,'FindAll','On','LookUnderMasks','All','IncludeCommented', 'on', 'BlockType','Scope');

fprintf('Number of Sope block : %d\n', length(ScopeBlks) );

delete(ScopeBlks);

unconnectedLine = find_system(gcs,'FindAll','On','LookUnderMasks','All','IncludeCommented', 'on', 'Type', 'line', 'Connected', 'off');

fprintf('Number of unconnected Line : %d\n', length(unconnectedLine) );

delete(unconnectedLine); % Issue point..

Hi,

I believe if you just want to delete the unconnected portion of the line, you can use delete_line() instead of delete. That will remove only the unconnected part of the line. I tried it out in 2020b release and it works.

Thank you,

If you would like to see which blocks are unconnected, get a handle to the ports of the block you would like to check, then use delete_line to remove unconnected lines. The example below will try to delete the unconnected Outport blocks within a loop.

open_system('test')
blks = find_system(bdroot, 'Type', 'block');
listblks = get_param(blks, 'BlockType') ;
for i = 1:length(listblks)
      if strcmp(listblks(i),'Outport')
          lines = get_param(blks(i),'PortConnectivity');
          if lines{1,1}.SrcBlock == -1
              disp(blks(i))
              h = get_param(blks(i),'LineHandles');
              delete_line(h{1,1}.Inport);
              delete_block(blks(i));
          end
      end
end
