(a) Write a MATLAB function [W,R] = house(A) that computes an implicit representation of a full QR factorization A=Q R of an m ×n matrix A with m ≥n using Householder reflections. The output variables are a lower-triangular matrix W ∈ℂ^m ×n whose columns are the vectors vk defining the successive Householder reflections, and a triangular matrix R ∈ℂ^n, n (b) Write a MATLAB function Q= formQ(W) that takes the matrix W produced by house as input and generates a corresponding m ×m orthogonal matrix
