Hi ,
I want to run a Simulink model in a .m file for loop and keep values of each iteration without changing in the next loop cycle. Is there any possibility for you to help me out with this?
In the following code, 'TestBlock' runs 2s and, sends a variable; 'theta' to the workspace. I want to store that theta value and next consequent theta values till the loop will be over.
P1=1:1:5;
P2=2:1:5;
for i=1:(length(P1))
for j=1:(length(P2))
P1_in=P1(i);
P2_in=P2(j);
sim('TestBlock');
end
end

If theta is a scalar,
P1=1:1:5;
P2=2:1:5;
SavedTheta=zeros(length(P1),length(P2));
for i=1:(length(P1))
for j=1:(length(P2))
P1_in=P1(i);
P2_in=P2(j);
sim('TestBlock');
SavedTheta(i,j)=theta;
end
end

Thank you very much Fangjun,
I encounter the following errors.
The following error occurred converting from timeseries to double:
Conversion to double from timeseries is not possible.
Error in pressureCombinations (line 13)
SavedTheta(i,j)=thetaw;
When I convert the format in to array, then the following error is again encountered.
Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is
401-by-1.
Error in pressureCombinations (line 13)
SavedTheta(i,j)=thetaw;

So theta is a timeseries or array, then replace with this
SavedTheta=cell(length(P1),length(P2));
SavedTheta{i,j}=theta;
Hi Fangjun,
I want to read those values at the end. What's the way of reading savedTheta 2D array.
Btw, this array consisit thousands of data as I increase the intervals of P1 and P2.
