Hi Phoebe,
The indexing error occurred because the 'Xtcounter' object is trying to access an element of 'xcounter' that does not exist. The xcounter variable depends on the value of the 'diagcounter' variable, which may have caused the error.
To resolve the indexing error in the code, kindly modify your code as shown below:
% Initialize array to store xcounter values at each diagnostic step
Xtcounter = [];
while time < tfinal
time = time + dt; % Update time in each loop
if ((int8(time / diagstep) * diagstep) == int8(time))
xcounter = ParticleCounterFun(x0, particleno);
% Increment diagnostic counter and store xcounter in Xtcounter
diagcounter = diagcounter + 1;
Xtcounter(diagcounter, :) = xcounter;
end
end
I have modified the code to ensure that each xcounter array is stored as a row in Xtcounter for every diagnostic step, rather than attempting to access individual elements.
I hope the above provided code will help you to resolve the issue!
