I am calculating Temperature when given altiude. For different values of h, the temperature will either fall under an equation or it will be a constant number. Is there a way to graph a continuous line that uses all of these segments? It is already showing a single point on the graph that is the h and calculated T value, I'd like that to show up on the graph as well.

function [h, a] = Temperature(T)
prompt = 'Altitude (m) ';
h = input(prompt);
if (h <= 11000)
    T = (h - 44332.30769230768) / -153.84615384615378
    
elseif (h <= 25000)
    T = 216.66
    
elseif (h <= 47000)
    T = (h + 47220) / 333.3
    
elseif (h <= 53000)
    T = 282.66
    
elseif (h <= 79000)
    T = (h - 115813) / -222.2
    
elseif (h <= 90000)
    T = 165.66
    
elseif (h <= 110000)
    T = (h - 48585) / 250
    
end
plot(T, h, 'o')
