Parallel Colt is a multithreaded version of Colt - a library for high performance scientific computing in Java. It contains efficient algorithms for data analysis, linear algebra, multi-dimensional arrays, Fourier transforms, statistics and histogramming.

The newest version!

Random r = new Random();
IHistogram3D h3 = new Histogram3D("AIDA 3D Histogram",10, -2, +2,    5, -2, +2,    3, -2, +2);
for (int i=0; i<10000; i++) h3.fill(r.nextGaussian(),r.nextGaussian(),r.nextGaussian());
System.out.println(new Converter().toString(h3));
