My code is currently supplying 2 constants of A only. How do I supply another 2 constants of B into the same function?
n=30;
% Initialization
T=zeros(n,n);
T(1,:) = 410; % Top
T(end,:) = 420; % Bottom
T(:,1) = 400; % Left
T(:,end) = 400; % Right
T_old = T;
% Constants of A
k1 = 0.02;
k2 = 0.33;
% Constants of B
% k1 = 0.04;
% k2 = 0.67;
for k = 1:20 %time steps
for j = 2: (n-1)
for i = 2: (n-1)
T(i,j) = T_old(i,j)*(1-2*k1-2*k2)+k1*(T_old(i-1,j)+T_old(i+1,j))+k2*(T_old(i,j-1)+T_old(i,j+1));
end
end
T_old = T;
end

Start with the code I posted in response to another one of your Questions, https://www.mathworks.com/matlabcentral/answers/857275-loop-never-stops#answer_725790
and subs() different k1, k2 values as desired.
If you were careful enough about how you proceeded, you could create 2D array of combinations of k1, k2 values, move those into the 3rd and 4th dimension, and subs() once, to get a single 4D array.... though visualizing the result could be tricky!
