Christopher Nix updated MATH-611:
---------------------------------
Attachment: SingularValueDecompositionImpl.patch
I have attached a patch file for the JAMA implementation, together with unit
tests for MATH-327, MATH-465 and MATH-583.
Additionally, I have removed the unit test testMatricesValues1 that tested an
implementation specific return value of getU() and getV().
> A fast and stable SVD implementation from JAMA

> Common numerical stability issues with the current SVD implementation, ie
> MATH-327, MATH-383, MATH-465, MATH-583 can all be solved by co-opting JAMA
> code that is within the public domain.
