GSL shell offers an interactive user interface that gives access to the GSL collection of mathematical functions. It is based on the powerful and elegant scripting language Lua. GSL shell is not just a wrapper over the C API of GSL, but offers a much more simple and expressive way to use GSL. The objective is to give the user the power to easily access GSL functions without having to write a complete C application. It also has a powerful module to produce plots or almost any kind of graphics based on data or functions.

Release Notes: This release improved the data table module by fixing bugs and by improving the interface. The Makefile based build was improved to support parallel compilation. LuaJIT was updated to version 2.0.2 including recent changes from the official repository. GSL Shell is also binary compatible with LuaJIT and a standard Lua DLL is included in the binary distribution.
Release Notes: The General Data Table implementation is now complete. All the related functions are documented in a specific chapter of the user's manual. A family of plotting functions to create plots based on a table's data are available and documented. The function for linear regression now correctly handles most corner cases and complex factor products. The functions to create tables and read CVS files were improved. A function for univariate interpolation based on gdt tables was introduced.
Release Notes: This release introduces the "general data table" type to manage data (strings or numbers) in tabular form like in GNU R with data frames. It introduces a whole family of functions that operate on gdt tables to easily make plots and statistical analysis. Like in GNU R, a function to fit data based on a linear model is introduced. The linear model can take into account both scalar and discrete factors. Support for plots with multi-level axis labels is introduced to improve plotting on data based on nested factors. The user's manual is updated with a new chapter on the gdt module.
Release Notes: With this release, the graphical user interface is now stable and completely usable. A major issue with the OpebBLAS library on Windows is now fixed. A new method to export in SVG format the whole window was added, and an integrated help system is introduced. The underlying Lua implementation now uses the latest stable release of LuaJIT2. Many bugs and problems have been fixed since the last beta release.
Release Notes: This beta release introduce a Graphical User Interface (GUI) for both Windows and Linux. The plotting system is also greatly improved, with much better font rendering quality. The system now use the OpenBLAS libraries for optimal performance on x86 CPUs, but a build with GSL CBLAS is still available. The system to add plot legends is simplified, the module for eigensystem resolution is now implemented, and an integrated help system is introduced.
