GSL shell

GSL shell is an interactive command line interface that allows you to access the functions provided by the GNU Scientific Library.

GSL shell can be used interactively to perform calculations with matrices or vectors but it does allow also to write complex user defined functions with the LUA scripting interpreter.

What is new in this release:

• A lot of work was done to improve the linear model function to treat correctly the corner cases and degenerate models. A functions to initialize GDT tables have been improved for greater simplicity. The function to create histograms was also improved over the first implementation. A new, useful, interpolation function for GDT table is also introduced.

What is new in version 2.2.0:

• 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.

What is new in version 2.2.0 Beta 2:

• 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.

What is new in version 2.1.0:

• This version adds several enhancements to the plotting system, adds support to save plots in SVG format, implements support for customized plot legends and customized axis labels, implements the VEGAS Monte Carlo integration functions, adds a new and more complete implementation of the Special Functions module, adds support for smart auto-completion based on the readline library, adds a benchmark page in the webpage to show comparisons with C-optimized code and JIT contributions, and adds various other minor improvements and bugfixes.
• Three new contributors have joined the project.

What is new in version 2.0.0:

• Many build problems have been fixed for Linux and Mac OS X.
• Many fixes have been done for the x64 platforms, and a couple of serious bugs with LuaJIT2 have been fixed for the ARM platforms.
• Thanks to LuaJIT2, GSL Shell now works on x86, x64, and ARM with full JIT support.
• Support for compiling on Mac OS X was added.

What is new in version 2.0 Beta 1:

• This is a major new version. LuaJIT2 is used as an underlying Lua implementation, giving a major speed improvement.
• The FFI module is used also to directly call GSL and other C functions.
• Many modules have been reimplemented in Lua using FFI calls, obtaining native speed performance.
• The functions are now better organized using modules.
• The operations on matrices complex or real are more simple, and the multiplication operator corresponds to matrix multiplication.
• A 'demo' function and a featured demo that simulate a spinless quantum particle in a step-potential have been added; try it with demo('wave').

What is new in version 1.1:

• Some bugs fixed, most notably a couple of bugs related to the X Window implementation.
• Added a module to read data in CSV format.

What is new in version 1.0:

• Many bug was fixed for this final release. A function to save() a plot as an image in bitmap format is now available.

What is new in version 1.0 Beta 2:

• put multiple plots on the same windows
• make animations
• have multiple graphical layers in a plot.
