jones_supa writes: GNU Octave — the open source numerical computation suite compatible with MATLAB — is doing very well. The new 3.8 release is a big change, as it brings a graphical user interface, a feature which has long been requested by users. It is peppered with OpenGL acceleration and uses the super fast FLTK toolkit for widgets. The CLI interface still remains available and GNUplot is used as a fallback in cases where OpenGL or FLTK support is not available. Other changes to Octave 3.8 are support for nested functions with scoping rules, limited support for named exceptions, new regular expressions, a TeX parser for the FLTK toolkit, overhauls to many of the m-files, function rewrites, and numerous other changes and bug fixes.
