Acknowldgemets

--------------

-I would like to thanks the contributors of all the excellent free

-softwares that made GSL Shell possible. In particular thanks to the

-GSL Team for their excellent work, to the Lua team for their excellent scripting language.

+If GSL Shell exists is thanks to the many high quality free software projects on which it is based.

-Finally, thanks to my girlfriend, Gosia, for her patience and her support.

+The GSL team have made a great works over the years to bring an excellent, well thought, library for C programmers.

+Their work is even more remarkable thanks to the complete and accurate documentation.

+The GSL library deserves the merit of having opened the way to access high quality numerical routines for the non specialists of FORTRAN.

+

+Many thanks also to the Lua community for publishing their work under a free software license and to Maxim Shemarev for his great AGG library.

+

+Finally I would like to thanks to my wife, Gosia, for her patience and her support.

GSL shell is an interactive command line interface that gives easy access

to the GNU Scientific Library (GSL) collection of mathematical methods for

numerical computations.

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.

GSL Shell is hosted at `Savannah <http://savannah.nongnu.org>`_, here is the `project page <https://savannah.nongnu.org/projects/gsl-shell/>`_.

-You can download the latest release of GSL Shell in the `download page <https://savannah.nongnu.org/files/?group=gsl-shell>`_. You will find the source code, a binary package that require GSL 1.14 (or more recent) and readline5.

+

+**NEW**

+ *The new GSL Shell 2 is in beta release*.

+

+ This new release of GSL Shell is a major change both in term of features and implementation.

+

+ First the functions are now organized into different modules for a greater clarity of the code.

+ Then the semantic of the arithmentic operations with numbers and matrix is now much more user-friendly.

+ The multiplication operator '*' it does perform now the matrix multiplication and you can mix freely complex and real number or matrices.

+

+ Under the hood there even more important changes since GSL Shell is now based on `LuaJIT2 <http://luajit.org>`_.

+ This latter is an highly optimized implementation of the Lua programming language.

+ LuaJIT2 is able to generate on the fly optimized machine code so that many programs can run at the speed of native code.

+ In addition, with the FFI module, you can call directly C functions opening the way to an incredible set of new applications.

+

+ The modules about numerical integration, ODE integration and non-linear fit have been *reimplemented* in Lua using direct FFI call to C functions.

+ The result is a greatly improved execution performance on par with optimized code.

+

+ Check the *demos* available in GSL Shell.

+ You may check the 'wave' demo that simulate a *quantum spinless particle in a step potential*.

+ Thanks to LuaJIT2 the demo run in realtime at an amazing speed.
