I need all 3 parts answered please!

Exploration 3.3.3 (a) Write a MATLAB function [L,U]-tridiaglu(A) to find the LU Decomposition of a tridiagonal matrix. any banded matrix with upper bandwidth p and lower bandwidth q. answers should be in terms of p and q. You may use big-O notation. (b) Now, write a MATLAB function [L,U)-bandedlu (A,p,q) that does the same for (c) Approximately how many arithmetic operations does each function require? Your When a matrix A is banded with bandwidthw, it is wasteful to store it in the traditional Exploration 3.3.3 (a) Write a MATLAB function [L,U]-tridiaglu(A) to find the LU Decomposition of a tridiagonal matrix. any banded matrix with upper bandwidth p and lower bandwidth q. answers should be in terms of p and q.
