The two actually look very similar. The community that I learned Uzawa from is very familiar with Sherman-Morrison. Uzawa might in fact be an iterative S-M ... the wikapedia page does not explain how to recover the solution Y and does not accommodate a non-zero RHS for the constraint equations. Both of which you'd want to do to be general.</blockquote>
