Index exceeds the number of array elements error

My code needs to make a new vector called Fuel for each value in the vector Payload, and I am getting an error that says "index exceeds the number of array elements. Could somone help me figure out where the error is an how to fix it?

Payload = [0:100:MaxPayload];

i = 1;

while Payload <= MaxPayload

Fuel(i) = MaxTakeOff - EmptyWeight - Payload(i) - TotalCrewWeight;

i = i + 1;

end

Try this:

while (i <= length(Payload)) && (Payload(i) <= MaxPayload)

That worked great! Thank you so much!

Suppose MaxPayload was 250, 0:100:250 is 0 100 200. All of the entries of that are less than MaxPayload so the loop would not terminate.

Even if MaxPayload were 200 then 0:100:200 is 0 100 200 and all entries of that are less than or equal to MaxPayload.

Your loop will never terminate until you get an error.

So woud you suggest I increment it by 1, or at least a smaller increment?
