If X is defined as in equation (3.6.1) and Xo is defined in (3.6.2), find a matrix

Question:

If X is defined as in equation (3.6.1) and Xo is defined in (3.6.2), find a matrix U such that Xo = XU. Note that C(X) =

C(Xo), so (3.6.2) is a reparameterization of (3.6.1). Clearly, Xo"! = XU"! =

X;3, so ;3 = u"! + v for some v with Xv = O. Find a matrix U* so that Hints: U is easy to find, and the right-hand side of the last equation essentially gives U*.
