I want to get the proper name of the connected port but the get_param gives me the incorrect names:

block_of_interest_params = get_param(block_of_interest,'PortConnectivity');
connected_inports_handle = find_system(block_of_interest_params(i).SrcBlock,'SearchDepth',1,'LookUnderMasks','all','BlockType','Outport','Port',block_of_interest_params(i).Type)
connected_block_nameport{i} = get_param(connected_inports_handle,'Name') %connected block portname

I need to have port names of the outport that are connected to In5 and In6.

and my incorrect result:

correct is when tags out2 are out1.

Thank you in advance for help!

I need the name: Out1 and Out3 not: Subsystem:2. It is possible?

Ewela 2021-10-12

The line:

get(get(a.Inport,'line'),'SourcePort')

get the error:

Error using get

Conversion to double from cell is not possible

@Ewelina Cholodowicz I hope this will solve your issue :)

Please let me know if you stuck at any point, or any point is not clear.

load_system('sampleModel')
block_of_interest = 'sampleModel/Subsystem1';
block_of_interest_PH = get_param(block_of_interest,'PortHandles');% get all ports
for i= 1: length(block_of_interest_PH.Inport)% loop through all inports
    lineHnd = get(block_of_interest_PH.Inport(i),'line');%get line handle to trace back
    if lineHnd~= -1  % if line handle is present
        SubName = get(lineHnd,'SourcePort');% get source port number of sub
        SubHnd = get(lineHnd,'SrcBlockHandle');% get source block i.e Subsystem
        OPName = get(find_system(SubHnd,'BlockType','Outport'),'Name');% get all outport name of subsystem
        GotoBlockName = OPName{str2num(extractAfter(SubName,':'))}% get specific outport name
        
        %add goto block logic below GotoBlockName have correct name
        
    end
end
GotoBlockName = 'Out1'
GotoBlockName = 'Out3'

The above code shows how to get outport name please add from and gotot logic below that
