Other than published examples or examples worked by hand, one thing that I have found useful is to compute target values using R (which I think does SVD), mathematica or other packages. That is obviously not infallible, but often brings bugs to the surface. Sometimes you can also use known analytical properties of the result to validate it (like what Al is suggesting). I haven't looked at SVD in a while, but there are likely other things that can be done there as well. Also, it is good to include examples that are known to be numerically challenging, ideally ones with analytical solutions that you know in advance. Sorry, but I don't have any of this at the ready for SVD. Poke about in the numerical linear algebra literature and you will likely find some good examples and boundary cases.
Thanks for working on this. Phil On 10/1/05, Kim van der Linde <[EMAIL PROTECTED]> wrote: > Hi All, > > In the past, I have plugged the JAMA SVD class to the matrix class of > commons.math.
