How can I create a script to automatically delete unconnected lines from my Simulink model in Simulink 7.6 (R2010bSP1)?

I would like to write a script to delete unconnected lines within the model.

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
