The aim of the code is to scour a .mdl and delete any mux blocks that are not connected to anything (outport) and then their input signals on that condition. On a side note I am a massive noob.
Start by determining the paths of all the mux blocks:
mux_list = find_system(model_name, 'LookUnderMasks', 'all', 'BlockType', 'Mux')number_of_mux = size(mux_list);number_of_mux = number_of_mux(1);
Then proceed with the operation. The operation successfully deletes mux blocks who's outputs are not connected to anything. However, it also deletes mux blocks whose outports are connected to masked blocks (rather than standard blocks) – this is undesirable and is the issue.
if number_of_mux == 0 disp('No Mux detected')else muxies=num2cell(zeros(number_of_mux,1)); % memory preallocation.
finalno = number_of_mux i = 1 for i=1:1:number_of_mux muxies(i,:)=mux_list(i); mux_current = char(mux_list(i)) linehandle_current = get_param(mux_current, 'LineHandles'); signal_current = linehandle_current.Inport; lolcats=get_param(mux_current, 'PortConnectivity') lolcats=lolcats.DstBlock deletequery = isempty(lolcats) if deletequery == 1 delete_line(signal_current); delete_block(mux_current); mux_del_list{:,i}=mux_current; else finalno = finalno - 1 end end disp([num2str(finalno), ' mux(s) of ', num2str(number_of_mux), ' were found and deleted. ']) disp(char(mux_del_list)) end
I presume I need some sort of paradigm shift in my approach to this to get it working as expected.
