SimplexNumerica is a scientific data analysis and visualization software for the Microsoft Windows operating system, developed by Dipl.-Phys.-Ing. Ralf Wirtz (started as former employee of the Fraunhofer Society for the Advancement of Applied Research in Germany). The program is used for creating publication quality graphics, particularly for research and science.
Overview
SimplexNumerica offers a wide range of features for numerical analysis, statistical evaluation, and graphical representation of data. It supports both 2D and 3D plotting, curve fitting, interpolation, and time series analysis. The software includes a built-in C++ scripting engine, allowing users to automate tasks and customize their workflows. The graphical interface is object-oriented and resembles Microsoft Office's Ribbon UI, making it accessible to users familiar with standard Windows applications. It supports multiple languages, including English, German, and French.
Key Features
- Data Visualization: High-resolution 2D and 3D charts, including scatter plots, bar charts, pie charts, and surface plots.
- Numerical Analysis: Tools for regression, FFT, DSP, FIR/IIR filtering, and statistical computations.
- Interpolation & Approximation: Includes splines, Bezier curves, and characteristic polynomials.
- Scripting: Integrated C++ scripting for advanced customization and automation.
- File Format Support: Compatible with formats such as *.csv, *.xls, *.xlsx, *.off, *.obj, *.ply, *.stl, *.wrl, *.mesh and more.
History
SimplexNumerica originated from earlier software developed at the Fraunhofer Institute for Laser Technology in Aachen, Germany. Its predecessor, Data Professional, was initially released for Atari/GEM systems and later adapted for Windows 95. Over the decades, the software has evolved significantly, incorporating modern visualization techniques and computational tools.
Licensing
SimplexNumerica is available in three editions:
- Freeware: For private, non-commercial use.
- Professional: Full-featured version available for purchase.
- Custom: Tailored solutions for specific projects or enterprise needs.
Reception
The software has been featured in German tech publications such as c’t Magazin, where it was praised for its ease of use and powerful visualization capabilities. It is often compared to other scientific tools like Origin and MATLAB, particularly for its plotting and data manipulation strengths.
