I am using it to debug other code that is deigned to compute SVDs, so I
actually want to understand the intermediate steps in constricting the SVD.
Nothing I have seen in the various books & net sources I have read seem to
indicate that the eigenvectors for U & V have any special requirements
other than being of unit length, but the experimentation in R seems to
indicate otherwise, hence my confusion.
