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)

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.
