help me to solve it

I Programming tas Your main task is to code the FDM prodecure in Matlab for solving the modeling problem below Suppose you have a meter long bar. The left end is maintain at 20 C and the right end is maintained at 30" C. A heating element is placed at 0.3 m from the right end, so that heat is highly concentrated around this location You must consider different models for the hcater as follows: 1. A step function where 100 W/m 0.G 0.8 m everywhere clsc 2. A step funton where 100 Wim 0.69 0.71 m everywhere clso 3. A Dirac delta function where 100 W/in z = 0.7 m everywhere else f(x) = . A normal distribution function where ( 2 where A be chosen so that the maximum value is around 100 W/m and ? is sufficiently small to model a highly concentrated heat source You Imust use minimum of 1000 divisions
