%Lenght of the plate ----------------------------------------------
lx= input ('Enter the desire value for x length:');
ly= input ('Enter the desire value for y length:');
%alpha ------------------------------------------------------------
k=143; %Thermal coductivity (W/m.C)
p=2.8*10^3; %Density (kg/m^3)
c=795; %Specific heat (J/kg.C)
alpha= k/(p*c); %Thermal diffusivity (m^2/s)
%Grid Spacing
h= input('Enter the desire grid spacing:');
while rem (lx,h)~=0 || rem (ly,h)~=0
fprintf ('Incorrect solution \n Please enter a value which results in an integer number:')
h= input ('Reenter the desire grid spacing:');
end
%Grid Spacing along lx and ly -------------------------------------
nc= (lx/h)+1; %Number of columns
nr= (ly/h)+1; %Number of raws
%Time step --------------------------------------------------------
dt= input ('Enter the desire time step:');
while dt>= h^2/(4*alpha)
fprintf('solution is unstable. Please return to dt and choose a smaller value for: %g\n', h^2/(4*alpha))
dt= input ('Enter the desire time step:');
end
%Fourier Number (fo) ----------------------------------------------
fo= alpha*dt/(h^2);
%Creation of vectors ----------------------------------------------
T1= zeros (nr, nc);
%Boundary conditions ----------------------------------------------
T1(end,:)=0;
T1(1,:)=50;
for i= 1:nr
T1(i,1)= 50-50/(nr-1)*(i-1)
T1(i,end)= 50-50/(nr-1)*(i-1)
end
%For loops for temperatura: (Ts + Tn + Tw + Te - (4-1/fo)* Tp)) * fo
T2=T1;
for t=0:dt:inf
T1=T2
for j=2:nc-1
for i=2:nr-1
T2(i,j)= (T1(i-1,j)+ T1(i+1,j)+T1(i,j+1)+T1(i,j-1)-(4-1/fo)*T1(i,j))*fo;
end
end
%check convergence
if max(max(T2-T1))<0.001
break
end
end
disp(dt*t)

I have now but still don't know how to do it. Matlab is not my thing at all and I struggle a lot to know how to do things

You can start out with imshow and then look into colormap and colorbar.

Hi Hdez,
You can simply plot using plot command -
plot(T2)
To know more about plot command, you can refer here, or if you want to know which types of plots can be plotted in MATLAB, you can refer here.
