Description
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.

created issue 
As there are more no bug reports on the current SVD implementation, this issue is not high priority.
