special-functions - Version 1.1 The special function calculator is a double interpreterspecialized in the mathematical special functions :Gamma, Bessel, Airy, Exponential integral, Clausen,Rieman Zeta, Hurwitz zeta etc... The first interpreteris a command line interpreter which can handle simplemathematical formula in which you can include variousspecial functions calls like the classical transcendalfunctions and the special functions. This interpreter(called SFL for Special Function Langage) can memorizevariables and formulas. Coupled with this interpreterthe graph drawing tool allows you to visualize a function.For more complexe computation a second interpreterbased on Lua engine is provided. Lua is a powerful andmodern scripting langage from which you can call themathematical special functions. There are more than 170special functions which have been wrapped both callablefrom SFL or Lua script. In the mathematical world if you need specialfunctions facilities there are not a lot of solutions :Mathematica, Maple, Matlab TM. If you do someprogramming only the GSL (Gnu Scientific Library)offers a good panel of functions. With this specialfunction calculator you have a small application inwhich you can use easily special functions for yourcomputation. You can also make complexe applicationusing the Lua engine.
