Hi,

I solved a radial heat generation problem. I would like to plot for different value of k_u and q_dot from center to the wall. This is my code, and any feedback would be greatly appreciated.

clear
close all
q_dot = linspace(3000,5000,10);
r = linspace(0.000000001,0.01,50);
k_u = linspace(1000,5000,10);
T =@(r,q_dot,k_u) ( - (q_dot/ (4*k_u))* r.^2 + (100/k_u)* log(r) + 2000 );
for i = 1:length(q_dot)
    for j = 1:length(k_u)        
        for k = 1:length(r)
            
        T_sol(i,j,k) = T(r(k),q_dot(i),k_u(j));
        
        end
    end
end
plot(T(1,1,:), r)
