MATHPLOT v3.7 - Mathematical function plotting program. Mathplot allows you to enter math functions using ordinary algebraic notation and immediately plot them. Cartesian, polar, and parametric functions are supported. Presentation quality plots are produced on the screen or LaserJet printer. Excellent program for anyone who needs to quickly visualize math functions. Requires 512KB, CGA, EGA, or VGA.

*** NONLINEAR FITTER v0.95 *** Fitter is an easy-to-use shareware DOS protected mode program for finding a minimum of sum of squares of an arbitrary nonlinear functions of up to five variables or, as a particular case, for approximating (using the least squares criterion) of a given data set with an arbitrary function. Modified simplex and Levenberg- Marquardt methods are used. The approximating function must be placed in a user-supplied dynamic- link library.

poly02.exe (v0.2) Simple program to manipulate polynomials using normal arithmetic operations: +, -, x, /, ^, and substitution. You can also perform operations of the calculus on polynomials, and evaluate them.

NEW: v1.3 Primenumber Generator for Linux, MSDOS, OS2 and Mac. Very fast 32 bit algorithm. Source code for all platforms is included. OS/2 ver. requires EMX-RT v0.9b

PRIMES - Prime List & Prime Factorization Generator Program It generates the list of the prime numbers in a textfile. It can generate the prime factorization (e.g. 644 = 2 * 2 * 7 * 23 ) of the numbers in another textfile. The upper limit of the lists can be given. (Maximum is 60000) FREEWARE by Balint Toth

STEFI - Graph Editor and Analyser Program Edit and analyse graphs: weights, matrices, components, Prufer code, min. cost path and tree, excentricity, center, topologic order, strong components and more. VGA required, mouse recommended. SHAREWARE by Balint Toth
