MATLAB: Where is inport value coming from

inportsimulink

I am trying to decipher a Simulink model that someone else wrote. Several blocks have inports labeled 'position'. But I can't figure out if 'position' is calculated during the simulation (though I expect that it is) or is pulled in from the workspace. If 'position' comes from the workspace, it must have another name; there are no variables in the workspace with this name.

Is there a way to trace and identify the value that goes into an inport?

See Importing Data to Root-Level Input Ports. In particular, you need to look at the Configuration Parameters > Data Import/Export > Input parameter.

You need to use the Data Import/Export Pane of the model's Configuration Parameters window to get data using the Inport block. See Importing Data to Root-Level Input Ports for more information.

See Load Data to Root-Level Input Ports

You need to arrange your data in time series form.

One of the format is like below:

dataIn.time = [0:10]'; % Depend upon your sample time and stop time
dataIn.signals(1).values = data.x; % x values at each step
dataIn.signals(1).label = 'x'; %Inport name

dataIn.signals(2).values = 'data.y'; % y values at each step
dataIn.signals(2).label = 'y'; %Inport name

Now enter dataIn in Configuration Parameters > Data Import/Export > Load from workspace > Input
