MATLAB: Find the name of last inport in sub-system

find_systemget_paraminport

Is there any way to get the name of last inport in sub-system using matlab code?

Best Answer

find_system(gcs, 'SearchDepth', 1, 'BlockType', 'Inport', 'Port', num2str(length(find_system(gcs, 'SearchDepth', 1, 'BlockType', 'Inport'))))

where gcs is the subsystem handle you want to search.

The "links" are so called Inport-Shadows

 inportShadows = find_system('my_model', 'FindAll', 'on', 'BlockType', 'InportShadow');

will return the "dublicated" Inports.

Hi,

just wanted to say that I solved my problem. In fact Lucas answer gave a valuable hint. In fact I had the full path to the inport as indicated by the observation that I was able to get_param() the 'Port' parameter. However, the set_param() function apparently expects the port path as a string argument while I was using a one-dimensional cell-array returned by find_system().

Also, you must not set a Port number larger than the actual number of inports in the subsystem, because this at least screws up the display and possibly more.

All I all, this is what works for me:

function [] = ShowInPort(name, show, port)
% find block of given name in current subsystem
block = find_system(gcb, ...
  'LookUnderMasks', 'on', ...
  'FollowLinks', 'on', ...
  'Name', name);
if isempty(block)
    error('No block named "%s" found in subsystem', name);
end
if show
  if strcmp(get_param(block, 'BlockType'), 'Ground')
      replace_block(gcb, ...
        'LookUnderMasks', 'on', ...
        'FollowLinks', 'on', ...
        'Name', name, 'built-in/Inport', 'noprompt');
  end
      % get a list of Inports 
      inports = find_system(gcb, ...
        'LookUnderMasks', 'on', ...
        'FollowLinks', 'on', ...
        'BlockType', 'Inport');
      % when changing the port number, be sure to never set a 
      % port number larger than the actual number of inports present 
      % in the subsystem
      set_param(cell2mat(block), 'Port', num2str(min(port, length(inports))));
  else
     if strcmp(get_param(block, 'BlockType'), 'Inport')
        replace_block(gcb, ...
          'LookUnderMasks', 'on', ...
          'FollowLinks', 'on', ...
          'Name', name, 'built-in/Ground', 'noprompt')
      end
  end

Thanks anyway.
