A new release of Octave has been announced.
"On November 26, version 6.1 of GNU Octave, a language and environment for numerical computing, was released. There are several new features and enhancements in this release, including improvements to graphics output, better communication with web services, and over 40 new functions"
There are quite a number of forum posts referencing Octave as well as scripts in the forum's Files section.
