... Lemma 2 . 1 Let S be a collection of square symmetric matrices A. If a matrix BES is a minimum ( i.e. , A≥B for all AE S ) then this minimum is unique . Proof : Suppose there are two such matrices B , and B. Then A≥B1 for all Ae S ...

... Lemma 3 . The rank of any matrix X is the same as that of X'X . Proof : We shall show that X and X'X have the same column null space ( hence the same column nullity ) ; since they have the same number of columns , it will follow that ...
