Interactive scientific graphing and data analysis software.
...The built-in analysis operations include column/row statistics, (de)convolution, FFT and FFT-based filters. Scripting Console support in-place evaluation of mathematical expressions and scrtipting interface to ECMAScript like dynamic scripting language(javascript). The GUI of the application uses the Qt toolkit. Periodic test builds are available here http://alphaplot.sourceforge.net/test-build.html
The metric project supplies, via the web, educational materials in mathematics and mathematics-based subjects. There are interactive explorations of mathematical ideas, self-test exercises, tools and tutorials.
GraphScript project is a network theory simulator based purely on Java and Java scripting engines.
It is intended to allow fast development, testing and visualization of network theory (graph) algorithms.
