"For Iteration" output index appears to perform parallel selector indexing in series instead

I am attempting to use a selector to compare the same index values from two different vectors for a logical operation. However, it appears the first selector goes through all index values (holds the last value) and then the next selector appears to index through all values so that the comparison logic is only using the last possible selection from the first selector to compare with each of the second selector values. Instead of the same index value for each selector (parallel).

Hi,

can you share any code?

It sounds as if you have something of the form

for J = 1:length(FirstVector)
    %some operation
end
for K = 1:length(SecondVector)
    %some other operation
end

where you should instead be using

for J = 1 : length(FirstVector)
    for K = 1 : length(SecondVector)
        %some operation
    end
end

But more likely you need

for J = 1 : min(length(FirstVector), length(SecondVector))
    t1 = FirstVector(J);
    t2 = SecondVector(J);
    %some operation on t1, t2
end

yes! that's right!

My issue was related to my initial conditions, rather than the "for iteration" block. i appreciate the help regardless!
