t_constant(n+1) = t_constant(n) + (alpha*dt/dx^2)*(t_constant(n)-t_constant(n-1)); in matlab

To solve the equation t_constant(n+1) = t_constant(n) + (alpha*dt/dx^2)*(t_constant(n)-t_constant(n-1)) in MATLAB, you can use a loop to iterate over each time step and compute the values of t_constant at each time step. Here's an example code to do that:

main.m
% Input parameters
alpha = 1;
dt = 0.1;
dx = 0.2;

% Initialize t_constant array
N = 100; % number of time steps
t_constant = zeros(N, 1);

% Set initial conditions
t_constant(1) = 0; % initial condition at n = 0
t_constant(2) = 1; % initial condition at n = 1

% Iterate over time steps
for n = 2:N-1
    t_constant(n+1) = t_constant(n) + (alpha*dt/dx^2)*(t_constant(n)-t_constant(n-1));
end

% Plot t_constant
plot(t_constant)
xlabel('Time step')
ylabel('t_constant')

In this code, we first initialize the t_constant array as a column vector with N elements. We then set the initial conditions at n = 0 and n = 1. Finally, we iterate over the time steps from n = 2 to N-1, and for each time step, we update the value of t_constant(n+1) based on the previous two values t_constant(n) and t_constant(n-1) using the given equation.

Note that you need to specify the values of alpha, dt, and dx according to your problem. Also, you may need to adjust the number of time steps N and the initial conditions to match your specific requirements.

Hope this helps!
