DataMelt 1.7

DataMelt (DMelt), is a platform for numeric computation, data analysis, statistics and data visualization. DMelt can be used for analysis of large data volumes, data mining, statistical analyses and math computations. DMelt creates high-quality vector-graphics images (SVG, EPS, etc.) that can be included in LaTeX and other text-processing systems. As a computational platform, one can use a number of languages, such as Python (Jython), Java, Groovy, Ruby (JRuby), BeanShell and Octave.

1.605 Aug 2016 00:07 major feature: Improvements for image processing and object recognition.
1.521 May 2016 18:22 major feature: Improved 3D graphics for scientific plots using OpenGL. Image examples in
1.417 Nov 2015 12:47 major feature: This is a maintenance release to improve usability, and restore compatibility with the original jHepWork program (2005-2012) and the book "Scientific Data Analysis.. " (Springer-Verlag, 2010). This version will also be consistent with the new book "Numerical computations .. on the Java platform" by Springer (2016). 1) Libraries have relocated and updated. Now Jython scans only systems/ math/ physics nnet/ directories. 2) Groovy was updated and relocated to the groovy/ directory. Same with jruby. 3) Added decision tree libraries and examples 4) For Linux/Unix/Mac, it runs Jython optimizer (first time start-up) 5) some redundant libraries were removed 6) jhplot.Web class similar to wget 7) Many other small bug fixes to improve usability.
