(c) What is the general reduced QR factorization for this matrixA?
(d) Compute the orthogonal projection onto the range ofA.
Note that this gives only the particular solution given in Part (b) above and not the entiresolution set. How might you recover the entire solution set from th QR factorization?(f) If ¯xsolves LLS for thisAandb, what isA¯x-b?
