#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
