MATLAB: How to find a variable in Simulink Model

model subsystemsimulink

I want to know the variable uses in demo sldemo_mdlref_datamngt.mdl.here assume in counter2 ,right click and if u see Model Reference Parameter there are two variables Params, ICs under Model argument values (for this instance).Can I know what it is and what are its values.I read help in Simulink but could not get relevant answer .On what basis these variables arte passed

The most general answer to your question is to use the Model Explorer. It's a great tool that lets you navigate through a model hierarchy and look at all the variables defined in different places.

You can also

Search for variables within the Model Explorer.
Right-click a variable in Model Explorer and select "Find where used".
Right-click any Simulink model or block and select "Find referenced variables".
Use the Simulink.findVars function to do search variables programmatically. [Example here]

FC is calculated in the mask initialization based on the parameters you enter in the mask: right-click on the fuel cell block, select "View Mask" and go to the "Initialization tab". You'll see the following code:

block = gcb;
%%DO NOT CHANGE THIS ORDER
FuelCellCback(block,'Update')
[FC, WantBlockChoice, Ts] = FuelCellInit(block);
powericon('SetInternalModels','set',block,WantBlockChoice);
FuelCellCback(block,'')

If you're using one of the few latest versions, the easiest thing to do is to open up that Gain block's parameters and right-click the text box where Rr is entered. This will give you two options to "open" or "explore" the variable.

This option is smart enough to figure out the location of the variable, which could be the base workspace, model workspace, a data dictionary, or a local variable in a masked subsystem.

If you don't have that option because you're on an older version, you can try right-clicking the Gain block and selecting "Find Referenced Variables" from the context menu. This will, for the most part, be equivalent to selecting that "explore" option; it will also open the Model Explorer.
