在 MATLAB Online 中打开

Since R2010b I think, you can use the "SignalHierarchy" property of a port to get the names of each signal in a bus. fo example, with the demo model 'busdemo', you can do:

busdemo([],[],[],'compile')
ph = get_param('busdemo/Bus Creator', 'PortHandles');
sh = get_param(ph.Outport, 'SignalHierarchy')

See details here:

This is awesome! You made my day! I unsuccessfully tried to figure out, how to find the names from the input signals, but this is just great!

One question: Is it possible that 'SignalHierarchy' is also working without updating/compiling the model? Your code also seems to work without it.

This Syntax is working for Simulink Model.

But for Library Model the 'SignalHierarchy' syntax is not executing. Because in Library model this option 'SignalHierarchy' is disabled.

Any way to get the Parameters of Input Port?

Thanks in advance.

How is the bus created? Do you want the signal name in MATLAB or Simulink. In Simulink, you can use the Bus Selector block to see the signal names. In MATLAB, maybe use Simulink.Bus.objectToCell

Bus is created using a Bus creator and one of the input to Bus creater is again a bus signal. I want the signal names in MATLAB.

awesome ! Is there any way to get the 'compiled data types' of these signal hierarchy ? I want to know them so that Simulink object can be created from these children's info.

Please let me know if if I can apply >>get_param(ph.Inports, 'CompiledDataTypes')

this method to signals also.

In 2020a if you have a bus selector block connected to the bus you can use its InputSignals parameter. The return value is a cell array with nested cell arrays for nested buses.
