Mathcad
Mathcad calculation software provides expanded support for the Calculation Management Suite, and builds upon the features of the previous version, such as XML and .NET support, to enable engineering and product development through the creation and management of engineering information. Provenance capabilities help to determine conclusively the source of a particular calculation, value or result. Document editing features offer right-click functionality and the ability to drag groups of worksheet regions to new documents. Also included are enhanced math functions, solvers, and IEEE-compliant arithmetic operations.
