SimplexNumerica is a data analysis and graphing (Freeware/Pro) software that can be used to visualize and analyze small (by interpolation) and large (by regression/approximation/reduction) data sets. It was developed by Ralf Wirtz It runs on Microsoft Windows and is available in English, German and French. It has a number of features and tools for data analysis, including data manipulation, data plotting, data fitting and statistical analysis. It also supports the import of various data formats, such as from various popular databases, spreadsheets and (CSV) text files. The program can create custom data visualizations, analyze data using statistical methods, and export the results to various formats. The software can be used to create attractive 2D/3D charts, graphs and diagrams. With a standard Windows 10/11 user interface, it makes complicated numerical mathematics easier to use, especially for beginners.

Programs can be developed using the built-in AngelScript C++ scripting language. The GUI has a state-of-the-art Microsoft Office 2023 design with many different skins, including the popular dark mode. The software comes with a large number of sample scripts and examples for many of its functions, including function plots, graph plots, math functions, histograms, FFT and IIR filters. It also has a wide range of algorithms for (spline) interpolation, approximation, data reduction, outlier testing, etc.

SimplexNumerica is part of the SimplexNumerica package that contains the following programs: Simplexety (a calculator), SimplexSlideShow (a slideshow maker), SimplexEditor (a HTML text editor), and SimplexIPC (a remote communication tool). The software is available for free download from the official website and various freeware sites.

In the c't magazine for computer technology 6/2013 several programs from different areas of science and technology were described. Here is an excerpt from the article: The evaluation and presentation of scientific data is one of the more tedious researcher duties. SimplexNumerica, an easy-to-use plotting program, provides a remedy. In addition to a large number of predefined 2D and 3D diagrams, the software shines with functions for importing and editing measurement data. The object-oriented structure of the graphical representation and a C++ script language ensure that hardly any wishes remain open when adapting to your own needs.

Here is an excerpt from c't magazine 14/2001, an article specifically about SimplexNumerica: Wherever numerical values occur, for example during measurements in physics lessons, during climate observations for geography or in the context of any statistical investigations, one wants to present them in a meaningful way. A very complex and powerful visualization tool, which is almost too good to be used as a mere teaching aid, is SimplexNumerica. The program has a venerable pedigree: for the Atari ST, its predecessor was sold years ago under the name 'Data Professional'. It masters special representations for the most diverse areas in school and study: geographers, biologists, chemists and electrical engineers can all make good use of it. Algorithm and function lists, diagram types and labeling options leave as few wishes unfulfilled as the options for the visual design of the results.

Here is the conclusion from ST Computer 6/92: The DATA program is highly recommended both for professional use in the evaluation and presentation of large amounts of data and for occasional use, e.g. in studies for the evaluation of practical experiments or the diploma thesis. The program impresses with its great ease of use as well as its high working speed. I did not find any major weak points. Nevertheless, a table generator, 3D graphics and perhaps pie graphics would round out the program (note: has been implemented over the years). In conclusion, I think I may say that DATA has now become a benchmark to which programs of this type must orient themselves.

Here is the conclusion from c't magazine 07/1990: ...is a professional program that allows very extensive mathematical data analysis. By the additional options one has various variation possibilities both of the mathematical functions and the graphic representation. It was possible to work with the program effortlessly on the Atari. ...very positive is that the author himself works intensively with his program and continuously extends and improves it and is also always open for suggestions from users. ...some suggestions for improvement concern the otherwise very detailed manual. Once the inclusion of additional application examples and the introduction of an index would be desirable ... with the graphic representation a 3D-graphic would be of advantage but also about this the author has already thought himself ...

Here is the conclusion from ST Computer 4/89: ...pleasing, however, is the open ear of the author (note: developer) for suggestions for improvement. Thus DATA (note: old name for SimplexNumerica) makes an all around successful impression. It makes it possible to display measured values professionally graphically, and that is exactly what it is made for. ...it has succeeded in setting up a standard against which other programs of this kind will have to be measured.
