Hello, I was running s simple for loop with a timer of 1 second as shown below:
r = ratecontrol(1);
n = [1 2 3 4 5]
for v = n
display(v)
waitfor(r);
end
Then I wanted to run parts of the array in different times, I though I would just make another array and run two for loops but MATLAB is single threaded.
what if I have three different arrays:
x = [1 2 3 4]
y = [10 3 6]
z = [3 8 0]
and I want to run X in a 1 second interval, y in 5 second interval and z in 10 second interval, but all running in same for loop in the same time?

Hi,
rateControl cannot be applied here. It executes only at a fixed frequency. You can use pause(t) to execute the loop at different fequencies. Below codes demonstrates the same
n = [1 2 3 4 5];
delays = [1 1 2 3 3];
count = 1;
for x = n
tic
disp(x);
pause(delays(count));
count = count + 1;
toc
end
