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
The latest download version of Extcalc is 0.9.3.
This is a beta version. The sofware must be tested and optimized at this state. When you miss a feature, please have a look
at the features page.
The latest download version of Concalc is also 0.9.3.
It uses the same mathematical algorithms as Extcalc and it
can be used in a console. The development of the console-specific part is finished, but it still needs the complete Extcalc calculator
and scripting algorithms.
Max Eliaser has written an interactive terminal interface for concalc.
It can be downloaded under http://gist.github.com/Max-E/5298687.
