Store a specific matrix value in a loop

Hello All,

I am working a project where I am calculating the temperature distribution of a plate using an iteration method and a 50x50 matrix. I would like to store a specific node value after each iteration - please see below Tm(41,41), so I can plot it later. However, I am having trouble figuring out how I can do this.

Any advice would be greatly appreciated. Thanks in advance.

for n=1:Inter
    Te=Tm;             
    t =t+dt;
    for i=2:Nx-1      
          for j=2:Ny-1
              Tm(j,i)= %..............................      
          end
    end
    
    Tm(41,41) % How to store these values? I would like to plot them later. 
%      
end 
return

iwant=zeros(Inter,1);
for n=1:Inter
    % your code
    iwant()n=Tm(41,41);
  
end
