How can i Extract data from Xsteam?

Hello,

I am trying to extract data from steam table for pressure range of 20bar and temperature range of 1000. I have written a code to call the data but it takes a lot of time and at end the values are just NaN. the code is as follows:

a = 1000;
b = 0.1;
c = 20;
h_out_SH = zeros(1,((a-1)/b));
L = length(h_out_SH);
M = length(h_out_SH);
for i = 1:L
for j = 1:M
    
    T_SH(i)= 1+b*i;
    p(j) = 1+c*j;

    h_out_SH(i) = XSteam('h_pT', p(j), T_SH(i)); 
end    
end

can someone please clear me this. Thank you.

I have the exact same problem! Can't seem to use values thath were just calculated as input in XSteam. Please help us!
