SVD/Eigenvector confusion
The documentation ?svd says U and V are orthogonal, i.e., that the transpose is the inverse. hope this helps. spencer graves

Is there a reason you are doing the SVD in such a complicated way? Why not use the svd function directly?
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.
