asap plz linear algebra

Question 7: Consider the matrix 1 on - a fan (a) Use Householder reflectors (by hand) to compute a (full/wide) QR factorization of A. (You may use software or a calculator for individual calculations, but show each step in exact arithmetic.) (b) Write a Matlab program hhar.m that uses Householder reflectors to compute a QR factorization of a general mx n matrix. (a) I have included the outline of a Matlab program (hhar.m) that you can start with There are three lines you need to complete in the code. They are labeled "TO DO (1)", "TO DO (2)", and "TO DO (3)". (b) Test your code on the matrix A given above. (c) In your homework file, include your Matlab code, show your resulting Q and R matrices, and confirm that QR = A.
