I got this question for my heat transfer class and dont know where to begin inputting into matlab to give me the correct answer.

The pictures illistrate the question and the correct solution

If you have any idea how i could solve this in matlab pls help

I wonder what your question is. The analysis completely solves the problem.

The T_i^p values for p = 0 are given by the last stationary equation for T(x), and the temporal changes for the T_i^p are given by the six updating equations (T_i^(p+1) = 0.375*...) at the end of the analysis.

My problem is how do i solve the problem on matlab,given the equations and solution.

What scripit would give me the same answer as the solution

Since you've said this is a problem for a class, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free MATLAB Onramp tutorial to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

My problem is how do i solve the problem on matlab,given the equations and solution.

Define an array T(6,6) where the first dimension refers to time (t) and the second dimension refers to space (x).

You know T(1,:), the temperatures at time t = 0 by the last x-dependent equation T(x) = ... .

Now use a loop from 2 to 6 to calculate the temperatures for t = 0.3, t = 0.6,..., t = 1.5 recursively from the six updating equations in the analysis.

More hints are not possible because this is a homework problem.
