Kalman Filter

Kalman filter technique is now widely being used in high energy physics experiments. There seemed to be, however, no light-weight easiy-to-use object-oriented package available in the market. We decided to design and develop a general-purpose Kalman filter package, KalTest, to satisfy such a need. KalTest is written in C++. It is based on ROOT and provides basic libraries for track fitting with Kalman filter technique. The package is distributed with some sample test programs to illustrate their usage. KalTest is now included in the "ILCSOFT" framework, but can still be used as a stand-alone application. For more details, go and take a look at our "KalTest" site.
