I would like to access the name of the variables of a generic Simscape block which is used in my model.

The function "get_param" works for block parameters, but not for block variables.

For example: suppose I have a Resistor block in my model; I am looking for a Matlab function which tells me that there exists a variable called "i", associated to this block

Hi,

In my understanding you want to access the variable names from a simscape model

you can use the following function

[names,values,units] = symReadSSCVariables(componentName)

It returns cell arrays containing the names, values, and units of all variables from the Simscape™ component called componentName.

Refer to the documentation for details.

Thanks

Exactly what I was looking for

Thank you

EDIT

It seems like the function symReadSSCVariables requires "Symbolic Math Toolbox". Is there a similar function which is available even if no additional Toolbox is installed? (i.e. only Simulink and Simscape required)
