how to make a loop for a simulation?

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

Please clarify why this doesn't help? This runs the model and updates the plot every 10 seconds per your specifications.

It seems like you can achieve the same result by using a Scope block with a Decimation factor of 10. Is there a reason you want to use PLOT instead?
