Colt (libraries)

Colt is a set of open-source libraries for high-performance scientific and technical computing written in Java and developed at CERN. Colt was developed with a focus on high energy physics, but is applicable to many other problems. Colt was last updated in 2004 (when Java 1.4 was the current release) and its code base has been incorporated into the Parallel Colt code base, which has received more recent development.

Colt contains, among other things, data structures and algorithms for offline and online data analysis, linear algebra, multi-dimensional arrays, statistics, histogramming, Monte Carlo simulation, and parallel & concurrent programming.
