Can we find simulink signal object used in the model using Simulink.findVars?

Can we find simulink signal object used in the model using Simulink.findVars.

Will you tell me how to find all the simulink signal object used in the model.

Hello Sainath,

Did you find the answer for this question. I am looking for the solution of this problem.

Answer 1

Yes. Make a simple example and you can find it out.

Updated in March 2024 using MATLAB R2022b.

Make a simple Simulink model, for example, a Constant block connected to a Gain block. Set the constant value as ConstA, label the output of the Gain block as SignalA and check "Signal name must resolve to Simulink signal object".

Creat ConstA=Simulink.Parameter(0) and SignalA=Simulink.Signal in base workspace

Create extra ConstB=Simulink.Parameter(0) and SignalB=Simulink.Signal in base workspace to experiment un-used data

Run variables = Simulink.findVars('ModelName') will return ConstA and SignalA.

Yes, it returned me the list of simulink.signal defined in base workspace. Even though they are used in simulink model am gettingthem in the list of unused variables. This is not happening for simulink.parameter.

Can you please share the script for this, Is there any way to find Simulink.Signal objects ?
