FREEWARE

RF21 for Windows is a scientific calculator, plotter, programming and  
numeric system in one. It allows for permanent installation of a user's own  
commented functions and libraries. Such user functions may have one or  
several arguments and values. Works as an archive at the same time, with  
integrated searchable database, to let you find and reuse materials created  
years ago.  
Predefined functions include the gamma, zeta, psi and Bessel functions,  
Gaussian error integral, cumulative Binomial distribution and more. On top of these and the user libraries, the program's numeric and plotting capabilities can be used, including:  
Numeric derivation and integration, Monte Carlo simulations, linear  
equations, matrix inversion and eigenvalues, nonlinear equation systems, n-  
dimensional function minimizer (Dennis & Schnabel method), Runge Kutta  
method for (systems of) differential equations, accelerated summation of  
series. Fraction reckognizer.  
Fast screenplots and an environment for designing printable plots, which  
may as well be exported to -.GIF and -.BMP files. Ample support for both  
simple and parametric plots, composition of several curves into one  
picture, drawing of directional or vector fields.  
Comes with standard libraries covering areas of science and mathematics,  
such as: stochastics and hypothesis testing, combinatorics, polynomial  
roots, geodesic travel routes, Keplerian orbits. With written documentation.  
Author's homepage contains a function reference.
