plotting T-U diagram using XSteam

for n=[1:220]
T=XSteam('Tsat_p',n);  
   vapor_u=XSteam('uV_T',T);
   liquid_u=XSteam('uL_T',T);
end

I'm trying to find temperatures for 1 through 220 but n saves only as 220. How would I get the code to run through all the values?

Hi Aldan,

the code is running through all the values, but it's not saving any of them. You need to do something like

m = 220;
Tsave = zeros(1,m);
vapor_usave = zeros(1,m);
liquid_usave = zeros(1,m);
for n = 1:m
    T = XSteam('Tsat_p',n);  
    Tsave(n) = T;
    vapor_usave(n)  = XSteam('uV_T',T);
    liquid_usave(n) = XSteam('uL_T',T);
end

which results in three 1x220 vectors of values.
