New Symbolic Engine
PTC Mathcad Prime 6.0.0.0 introduces a new symbolic engine.
User Interface Location: N/A
Release: PTC Mathcad Prime 6.0.0.0
Benefits and Description
PTC Mathcad Prime 6.0.0.0 introduces a new symbolic engine that will eventually replace the legacy symbolic engine. This new symbolics engine will be used by default in your worksheet, though you may switch back to the legacy symbolics engine from the Calculation Options menu for this release.
The new symbolics engine will cover all the same functionality that was available with the legacy symbolics engine but will allow for more flexibility in adding user driven functionality and enhancements moving forward.
* 
The new symbolic engine in PTC Mathcad Prime 6.0.0.0 operates to a specific set of calculation rules and as such differs in several ways from the legacy symbolic engine in previous versions of PTC Mathcad (please refer to Help documentation for information on some of those differences). For this purpose, the legacy symbolic engine is also available in this release (it will be removed in a future release). It is recommended that you review the results of your symbolic calculations using the new symbolic engine and if you encounter an issue that prevents you from using it, switch back to the legacy symbolic engine and report the issue to PTC via technical support. PTC appreciates and will actively review all feedback to determine what changes need to be made in future releases of Mathcad to make sure the new symbolic engine is functionally rich for all users.
