Phil Steitz updated MATH-355:
-----------------------------

    Affects Version/s: 2.1
                       2.0

Anyone interested in implementing this?  Should we move this to the wishlist?

> There has been a lot of recent activity on the SVD algorithm for Commons Math.  The SVD
has also been in the news lately because of the development of a new algorithm that is both
faster and more accurate than previous algorithms.  Given the importance of the SVD in many
applications it would be useful to have a Java implementation of this new algorithm in Commons
Math.
