Origin Pro 8.5.1 SR2 Build 315 Portable | 164 MB
The most powerful scientific package for data analysis and processing. It is considered the de facto standard in many research laboratories. OriginPro is a universal means of statistical and mathematical functions, handling data files, charting and graphs of these functions on the data arrays, as well as the development tool specialized mathematical software and visualization of image data.
Integration with data collection systems such as LabView, DasyLab, LabWindows ... Compatible with MathLab, MathCad, Microsoft Office ...
Origin includes the full version of a library of numerical algorithms from the NAG Mark VII Numerical Algorithms Group, Inc. (NAG ®). These well-established and proven algorithms provide the user with ample opportunity for the calculations, from simple statistics and Fourier transforms, linear algebra and ending with a multi-dimensional analysis. All library functions are available to call the NAG in Origin C, thus providing a platform for developing applications that require complex numerical calculations.
I'd add that even 10t years, all scientists are familiar with this program and force the students to draw graphics in it to graduation.
