MATLAB: How does resizing blocks to same size work in Simulink

resizeresizingsimulink

When I use Format->Resize blocks -> Resize block to same size , I am not sure what determines the size of the resultant blocks. If I have three blocks of different sizes, and resize them to same size, how does simulink decide the block whose size is taken as the reference to apply to all the other blocks ?

The block to whose size all the blocks will be resized is highlighted in white square corners as shwon in the attached figure (resize_reference.jpg). After selecting the blocks to resize you can change the default reference block by clicking on a block (that is one of selected blocks) that you want Simulink to take as reference. You can see the highlighting of white square change when you do this.

Well, I answered my own question...PortConnectivity is the parameter I was looking for. Here is some code that will "clean up" the input and output ports for a subsystem like that above (assuming input and output port blocks are connected to the subsystem block). Make sure you select the subsystem to clean-up first!

% get the subsystem port handle positions
pc = get_param(gcb,'PortConnectivity');
% distance from the subsystem to the port
offset = 200;
for i = 1:numel(pc)
      % position of port connector
      y = pc(i).Position(2);
      x = pc(i).Position(1);
      % port block handle and size
      if isempty(pc(i).SrcBlock)
          ph = pc(i).DstBlock;
          off = -(offset-50); % asthetics here...related to the width of the port block
      else
          ph = pc(i).SrcBlock;
          off = offset;
      end
      % port block dimmensions
      pp = get_param(ph,'Position');
      w = pp(3)-pp(1);
      h = pp(4)-pp(2);
      % adjust position of port block
      set_param(ph,'Position',[x-off,y-h/2,x-off+w,y+h-h/2]);
  end
