Funiter (short for Function Iteration) is an application developed for educational purposes as a laboratory, generating graphs of several types for iteration of real and complex functions, with comfortable switching between related types of graphs. Originally developed in the context of courses at the University of Nijmegen (Netherlands) for highschool students with a special interest in beta-studies.
There are various releases for this software, here you will find a short description for each version:
The original Funiter 2.1 for DOS which is released as "freeware".
It is not my intention to further develop this release, though if you find a bug I will look into it and try to solve it. It was written in Turbo-C++ 3.0 and the code is a complete mess.
A version (2.2 and higher) for Linux which is released as "opensource".
Finally I decided that I would like to port the original DOS version to Linux using gcc and the game library Allegro. The advantages are a higher portability, and less work for me porting numerous lines of code :-). It has the same look-and-feel as the original version and is released under the General Public License (GPL) .
A version (3.x) for Windows 95 and higher which is released as "opensource".
When I started a new version I couldn't decide which development tools to use, and tried Delphi first. This version is the result of a couple of months working with Delphi. I didn't abandon it since it has the typical Windows look-and-feel which some users might like. This version is released under the General Public License (GPL) .
