SimplexNumerica is a graphing and data analysis software application 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.

It covers applications such as curve fitting (Regression, Approximation, Interpolation, FFT, etc.) and time-series processing. It comes with a fully functional C++ programming language based on Angelscript. SimplexNumerica is primarily known for its graphics capabilities, and like Origin and other similar programs, is often used to generate plots for scientific and statistical publications.

Features[edit]

SimplexNumerica is based on the high-resolution graphical environment called SimplexGraphics. The program can generate different types of 2D and 3D plots (such as scatter, bar, pie, meter, contour and surface plots) from data that can be imported from well known data formats (like CSV, MS Excel, etc.) but also from more exotic formats, e.g. from SCADA systems like Siemens WinCC or Citect; GPX files for GPS navigation with an integrated GPX editor based on OpenStreetMap; GRETL econometrics package import; Data access from SQL Databases (e.g.: Oracle, MS SQL Server), etc.

The user interface sets up to the MFC extension library called BCGControl. In addition to the in-built graphics, charts from the plotting library ChartDirector can be selected. Legend are drawn like Webpages in HTML and/or Reports in Rich Text Format (RTF), so that MS Word text can be copied directly into the evaluation pages.

Reference[edit]

In the c't magazine for computer technology 6/2013 (see literature section) several programs from different areas of science and technology were described. Only Origin, Simplexety and SimplexNumerica were listed as evaluation programs. Simplexety and SimplexNumerica are from the same developer. 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 (see Literature section):

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 (see literature section):

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 (see literature section):

...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 (see literature section):

...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.
