    clc
    close all
    clear all

    L = 10/100;
    N = 20;
    dx = L/(N-1);

    T = zeros(N,1);
    Tb = 200;
    Tamb = 20;
    h = 50; %W/m2K
    k = 250; %W/mK

    X = h*dx/k;

    z = 5000;

    for j=1:1:z

    T(1,1) = Tb;

    for i=2:1:N-1

    T(i,1) = ( T(i+1,1) + T(i-1,1) )/2;

    end

    T(N,1) = ( X*Tamb + T(N-1,1) )/(X+1);
    plot(T);
    %hold on;
    end

    what is the doubt Manoj? If you need someone to explain the code please raise a ticket with the zoom meeting. An Engineer from flowthermolab will clarify it.
