How to build, connect to target and run a simulink model with GUI?

Ive made a simulink model and a GUI over which I insert the values of the variables used in the simulink model and when I insert those values and run the model over the GUI with

load_system('untitled'); set_param('untitled','SimulationCommand','start');

everything workes fine, and I can see the end result in the GUI axes.

Now the problem is when I put the model in real-time, it just wont work. I need to somehow build the model, connect to target and run it. I want to be able to follow the results in the axes in the GUI.

I hope somebody can help me!

If you'd like to access data during simulation, please follow the methodology described here.

This didnt really help me. Isnt there an overall code that does this job? Something I can just implement in my .m ???

Perhaps you're looking for something like this: GUI for Setting Simulink Model Parameters - this has everything but the runtime data part.

There are also several uploads on File Exchange:

Cant find the answer here. my simulation is very simple and I just want to view the scope results in real time in my GUI axes, but cant fix it.

Amir: That specific task can be accomplished by the technique described in the documentation linked in my original answer. Not sure why it didn't help you. Are there error messages?

is there a way to make a loop to pause my simulation every 10 seconds and plot the result and then continue the simulation and pause again and plot,... end time is 1000.

set_param(gcs,'SimulationCommand','start'); set_param(gcs,'SimulationCommand','pause'); % pause after 10second plot( ) set_param(gcs,'SimulationCommand','continue'); set_param(gcs,'SimulationCommand','pause'); % pause after 10second plot( ) set_param(gcs,'SimulationCommand','continue'); set_param(gcs,'SimulationCommand','pause'); % pause after 10second . . .

plot( )
