Updating Simulink Block Parameters using Matlab Scripts

Hi,

I am working on an application which involves me to write a script to automatically launch a Simulink Code and Run it.

I am able to load the model and run it using the 'Sim' command. I am also able to initialize parameters of the blocks using the 'set_param' command.

What I am not able to do is to change the values of these parameters dynamically while the Simulink Model (with end time as inf) is running? Is there a way to implement this?

E.g.:

cd C:\Users\INSL-CustED01\Desktop;

Sine_Wave;

sim('Sine_Wave');

set_param('Sine_Wave/Offset','Value','10');

Starts running the Model which has a Sine Wave Block with a Scalar 'Offset' being added to it. The model starts with an offset of 10. Now, I want to write additional commands to dynamically change the Value of Offset while the Model is running.

set_param(YourModel, 'SimulationCommand', 'pause');
set_param(YourBlock, parameter, value);
set_param(YourModel, 'SimulationCommand', 'continue');
