Accessing parameters in encrypted models

I have an encrypted Simulink model with some tunable parameters. I can change them by right-clicking on the model and choosing 'Block Parameters (ModelReference)'. However, unlike other (nonencrypted) blocks, I can't change them by using 'set_param'. Is there any way of accessing these parameters from the command line? I'm using Simulink R2015b.

Hi Magnus,

When dealing with an encrypted Simulink model, you are limited in how you can interact with the model's parameters from the command line. In general, encrypted models restrict certain functionalities to protect intellectual property, which includes direct access to parameters via set_param. However, you can still change tunable parameters if the model author has provided a mechanism for doing so.

Here are a few approaches you can try:

Approach 1: Use Model Workspace Variables

If the parameters are defined in the model workspace, you can modify them using the get_param and set_param functions to access the model workspace and change the variables.

Approach 2: Use setVariable Method

If the parameters are stored in a model workspace, you can use the setVariable method to change their values.

Hope this helps.

@arushi, Thanks for the answer. Unfortunately neither approach worked, so I guess the authors have not provided access to these variables from the command line.
