#Homework 5 2.)
The LU decomposition is excuted by the functions lu_tridiag.m.
The function solve_tridiag.m solves the x vector in the equation Ax = B
The test_array.m function then creates the matrixs that will be decomposed.
3.)
The table below compares the error between the created code and AN\b
