Using SimEvents results in Matlab

Hi,

I want to change a parameter from 1 to 60 (1:1:60) in SimEvents and run the simulation. I might need to that for other parameters too so I thought of using a for loop in Matlab to do that. I used the "To Workspace block" to export my simulation results into the worksapce and when I run my simulation it is working and I can see the results being stored in an array. But the problem is when I use the for loop in Matlab to run the simulation then I get an error and it is not working. Any idea that why is it working when I run the simulation model itself and it's not when I run it from the Matlab environment?

Here is my simple code in Matlab:

clc

close all

Period = 0;

for i=1:60;

    Period=Period+1;

    sim('concreting1','SaveOutput','on','OutputSaveName','Timing');

SumTruckWaitTime=sum(simout(:,1))

MaxTruckWaitTime=max(simout(:,1))

end

That's is the warning that I get:

Reference to a cleared variable simout.

Error in IntervalChange (line 10)

SumTruckWaitTime=sum(simout(:,1))

That's the to workspace block in my simulation model:

and it is actually working when I run it from the SimEvents environment:

Assign the output of sim to simOut.

simOut = sim('concreting1', 'SaveOutput','on');
z = simOut.get('Finaloutput'); % Finaloutput being the name of the output you want

It worked! Cheers

Hi again,

I need to store the time that an event occurred in the simulation too. For instance an entity leaving a queue in a specific time. How should I make this work? I am trying to use 'SaveTime', 'on' and the "Discrete Event Signal to Workspace" block but, I can't make it work!
