I've made a simulink model and I want the simulaltion after starting it to go into a loop that will pause (plot) and then continue the simulation. Can anybody help me with this?

set_param('modelZaGui1','SimulationCommand','start');

go into loop----------

set_param('modelZaGui1','SimulationCommand','pause'); % pause after 10 seconds

plot ( )

set_param('modelZaGui1','SimulationCommand','continue');

set_param('modelZaGui1','SimulationCommand','pause'); % pause after 10 seconds

plot ( )

and to go like this to the end of the simulation. Simulation time is 1000 and it should pause and plot after ever 10 seconds.

1) This is kind of awkward. Is there a reason you can't use the built in "Scope" block to accomplish this?

2) If you must do it this way, I suppose you could use the "Assertion" block to pause the simulation as described in the help for Controlling Execution of a Simulation. Add a modulus calculation to get "every 10 seconds". (Example model attached.)

Your main loop could then just wait for the simulation to pause, then call plot, etc, until the simulation is stopped.

%init so they have some value at t==0
ScopeData.time=[];
ScopeData.signals.values=[];
set_param(bdroot,'SimulationCommand','start')
% outer loop for the full simulation
while ~strcmp(get_param(bdroot,'SimulationStatus'),'stopped')
    pause(.001)  % give the plot a chance to update 
    if strcmp(get_param(bdroot,'SimulationStatus'),'paused')
        plot(ScopeData.time,ScopeData.signals.values);
        set_param(bdroot,'SimulationCommand','continue')
    end
end

The problem is that its a real-time simulation and Im using GUI, there is only one button, the START button. I want the scope results to plot on the axes and I cant get any values if I dont pause the simulation, soooo this was supposed to be a trick, pause---plot---continue---pause---plot... so your answer doesnt really help me
