MATLAB Help - Beam Deflection Finite Difference Method

Here I solve the simple beam bending problem fixed at two ends with finite difference method.

Textbook:
https://www.amazon.com/Numerical-Methods-Engineers-Steven-Chapra/dp/0073401064
The specific chapter is 27.2.3
E is the modulus
I is the moment of inertia of the cross section about its neutral axis.
It's possible to obtain an analytic solution to this problem but here I show the numerical approach.
