plotting; Leverage standard, readable mathematical expressions within embedded program constructs; Vector and matrix operations, including eigenvalues and eigenvectors; Curve fitting and regression analysis; Statistical and design of experiments functions and plot types, and evaluation of probability distributions; Import from and export to other applications and file types, such as Microsoft Excel and MathML; Cross references to other Mathcad worksheets; Integration with other engineering applications, such as CAD, FEM, BIM, and Simulation tools, to aid in product design, like Autocad, Ansys, Revit. Although Mathcad is mostly oriented to non-programmers, it is also used in more complex projects to visualize results of mathematical modeling by using distributed computing and coupling with programs written using more traditional languages such as C++. Current releases As of 2022, the latest release from PTC is Mathcad Prime 8.0.0.0. This release is a freemium variant: if the software is not activated after a Mathcad Prime 30-day trial, it is possible to continue using PTC Mathcad Express for an unlimited time as "PTC Mathcad Express Free-for-Life Engineering Calculations Software". This freemium pilot is a new marketing approach for PTC. Review and markup of engineering notes can now be done directly by team members without them all requiring a full Mathcad Prime license. The last release of the traditional (pre "Prime") product line, Mathcad 15.0, came out in June 2010 and shares the same worksheet file structure as Mathcad 14.0. The last service release, Mathcad 15.0 M050, which added support for Windows 10, was released in 2017. Mathcad 15.0 is no longer actively developed but in "sustained support". Computer operating system platforms Mathcad only runs on Microsoft Windows. Mathcad Prime 6.0 requires a 64-bit version of Windows 7, Windows 8.1 or Windows 10. Until 1998, Mathcad also supported Mac OS. Support Starting in 2011 (Mathcad 15.0) the first year of maintenance and support has been included in the purchase or upgrade price.
