You can either use a for loop
for t = 2 : 200
T(t) = T(t-1) + K * deltat * (F-T(t-1))
% Quit once it drops below 0
if T(t) < 0
break
end
end
Or use a while loop
maxIterations = 200
T(1) = initialTemperature
loopCounter = 1
while loopCounter < maxIterations && T(loopCounter) > 0
loopCounter = loopCounter + 1;
T(loopCounter) = .....whatever
end
