Modify the following code to solve the diffusion equation with Neumann boundary conditions using finite differences.

Modify the following code to solve the diffusion equation with Neumann boundary

For the code "[D,x]=cheb(N);", cheb() is one of the codng functions within chebfun, an open-source package for computing with functions to about 15-digit accuracy. In order to access the package,you will need to go to chebfun.org to download it.

Need help!! Please provide a step-by-step solution through the use of MALAB code along with a detailed explanation!!!! It is alright if you handwrite the step-by-step solution but I would prefer the solution to be shown in MATLAB code. This is very URGENT!!! PLEASE reply as soon as possible!! Thank you!!
