FC$03$USE MATLAB TO SOLVE THE FOLLOWING PROBLEM: Determine the numerical solution of the homogeneous $1-$D Heat Equation $=$ a at au ax which satisfies the initial condition: u$($x$,0)=$ x$,0$ using the FTCS Method from t $=0$ to t $=0\mathrm{.}3,$ with a$?=1.$ Create a three$-$dimensional $(3$D$)$ surface plot, and select a suitable value of Ax and At that will ensure a smooth plot and the stability of the solution.
