A few months ago I wrote about Visual Numerics and the release of their
numerical library for .NET applications. Now they're out with release
3.0 of the Java version of their library, and once again it's a very
spiffy package. If you're doing any sort of heavy number-crunching
(whether scientific, business, or otherwise), you should take a look at
the various Visual Numerics offerings.
Like their other products, JMSL is 100% native language code - in this
case, 100% Java(TM). That makes it easy to integrate it with your other
Java code, and means that you can use the same tools to work with the
library code that you use with everything else.
JMSL offers an immense selection of mathematical, statistical,
financial, and charting classes, together with extensive documentation
and sample code. As a 3.0 product, you'd expect some new features, and
you'd be right. This version includes:
- A robust neural network implementation
- Some additional regression modeling and forecasting algorithms
- Hierarchical cluster analysis for finding groupings in your data
- "Heat Map" charts - these can be used to show three types of
information at once by combining two dimensions plus a color. They have
a nifty demo of packing hourly temperature measurements for an entire
year into a single heat map.
In addition to emphasizing the company's commitment to providing native
language versions across a wide variety of platforms, JMSL 3.0 also
showcases some new boundaries. There is specific functionality here for
bioinformatics researchers, and of course the ability to easily set up
complex neural net processing will be a boon to anyone doing complex
forecasting. So even though there are some old classic algorithms here,
there are also new frontiers to explore. Plus as a .NET person I enjoy
this as a probable preview of some things we might see in the next C#
library (though that's just speculation on my part).
If you'd like to know more, you can view online demos or get an
evaluation copy of the software by filling out the appropriate forms at
the Visual Numerics Web site.
