Unformatted text preview: C ( A ) where: A = 1 1 1 1 1-1 1-1 1-1 . (b) Find the projection matrix P for projecting onto C ( A ) . Recall that with the factorization A = QR , the projection matrix P = A ( A T A ) ?1 A T becomes QQ T . (c) Check your answer for P by computing Pa 1 where a 1 is the ﬁrst column of A . 1...
