I’m looking for a fast library to compute SVD (Singular Value Decomposition) in Java.

I’m looking for a fast library to compute SVD (Singular Value Decomposition) in Java.
I have already tried some libs I’ve found and I’ve done some benchmark (the values show the average time of my benchmark run…) It’s not really a valid benchmark, but it was tested on the data I need to process, so enough for me..

  1. Jama – 152 102ms
  2. ujmp – 156 603ms
  3. Commons Math – 183 877ms
  4. colt – 203 866ms
  5. jblas – way slower…

I don’t really expect to find something faster than Jama, but I can give it a try… Can you recommend me some other library? Thanks!

edit:
I have found a nice page with benchmark of linear algebra libs, so I guess that concludes this question… EJML looks promising…
