MATLAB: How to fix a graph with loop

graphsloops

Sorry, I am new to MATLAB, so bear with me. I am trying to plot a graph which shows me the values of Y_B for T = 600:10:850, where k1, k2 and k3 vary with T. Instead, I am given a blank graph with only 599 to 601 on the x axis. Heres my matlab code
MATLAB code
 for i = 1:25
    T(i) = 600+10i;
    k1(i) = 10^7*exp(-12700/T(i));
    k2(i) = 5*10^4*exp(-10800/T(i));
    k3(i) = 7*10^7*exp(-15000/T(i));
    t = 0.2;
    Y_B(i) = (k1(i)*t*(k1(i)+k3(i)))/(((k2(i)*t)+1)*(k1(i)+k3(i))*(1+(t*(k1(i)+k3(i)))));
end
plot(T(i),Y_B(i));

Best Answer

You do not need for loop:
T=600:10:850;
t = 0.2;
k1 = 10^7.*exp(-12700./T);
k2 = 5*10^4.*exp(-10800./T);
k3 = 7*10^7.*exp(-15000./T);
Y_B = (k1.*t.*(k1+k3))./(((k2.*t)+1).*(k1+k3).*(1+(t.*(k1+k3))));
plot(T,Y_B);
