I've uploaded a .pet here extcalc-0.9.2.pet (980kbytes)Extcalc is a scientfic graphic calculator for Linux.
Extcalc is designed to use the full performance of a modern Computer for mathematical calculations.
Here are the main qualities:
* Calculating all standard mathematical operations on a Qt-based interface
* Usage of special functions like integration and differentiation
* Drawing different types of 2D- and 3D-graphs with OpenGL-Acceleration
* Function-analysis features for all supported graph types
* Integrated C-like script programming language, script editor, programming examples
* Text-based version to use on a console
This needs QT AND openGL libs to run. Start by either typing extcalc, or use Menu->Calculate->Extcalc.
N.B For pup4, you need to install qt-3.3.8.pet and then reboot.
