Compose two separate Matlab codes. They both have to be written as functions and each function needs to interact with the end user. Your code only needs to solve for the missing temperatures for this specific and particular problem.

$-$ Each of your functions will prompt the end user to enter the $4$x$4"$A$"$ matrix

$-$ Next, it will ask for the $4$x$1"$B$"$ matrix.

Finally, it will prompt for the convergence criteria.

With this information at hand the program will use the Gauss$-$Seidel method and the Jacobi method to return temperature values for nodes T$11,$ T$12,$ T$21,$ and T$22.$ These values need to be reported to $4$ decimal places
