Java Least Squares fitting library.
This is a small least squares fitting library made in java. It was originally used in the development of an image analysis tool SpeckleTrackerJ. Which has a lot of functions, this is a smaller package that only does the least squares portion. It is being written to include tests and a few more features.
SpeckleTrackerJ can be found at: http://athena.physics.lehigh.edu/speckletrackerj/
and the source code is hosted at google code. https://code.google.com/p/speckletrackerj/
