Hello,
I want to iteratively plot the results of my while loop, however, I end up with either one point on the graph as the output, or a blank graph.
Any help would be greatly appreciated,
Thank you

h = 0;
while h <= 11000
T = 15.04 - 0.00649 * h;
P = 101.29 * ((T + 273.15)/288.08).^(5.256);
rho = P/(0.2869*(T + 273.15));
h = h + 10;
end
plot(h,rho)

h = 0 : 10 : 11000;
T = 15.04 - 0.00649 * h;
P = 101.29 * ((T + 273.15)./288.08).^(5.256);
rho = P./(0.2869*(T + 273.15));
plot(h,rho) % if you want to see the movement use comet() instead of plot()

Hi,
Use an array to store the values so that you can plot them.
% ---------------------------------------------------------

clc
clear
h = 0;
i = 1;
while h <= 11000
T = 15.04 - 0.00649 * h;
P = 101.29 * ((T + 273.15)/288.08).^(5.256);
x(i) = h;
rho(i) = P/(0.2869*(T + 273.15));
h = h + 10;
i = i+1;
end
plot(x,rho)
Regards

I agree @madhan ravi. Its a better approach.
