Identify nodes from terminals in circuit object

Consider a simple RF Toolbox circuit object:

ckt1 = circuit('example_circuit1');

add(ckt1,[2 3],resistor(50))

add(ckt1,[3 1],capacitor(1e-9))

Two elements, three nodes as follow:

The problem is: when creating ports, mapping between nodes and ports can't be known just from the object. Ports can be created using:

setports(ckt1,[3 1],[1 2])

OR, a different circuit topology by defining different ports:

setports(ckt1,[2 3],[1 2])

How to know the topology from the object after creation??? (i.e. when I receive the circuit object as a result of impedance matching)

In case somebody has the same problem: I found an easy solution for the specific case of impedance matching: you can use the "Matching Network Designer", either directly to generate the networks, or to analyse a matching network result:

mnobj = matchingnetwork(..); %whatever the configuration is

matchingNetworkDesigner(mnobj) % analyse results in the app
