Create your own applications with SDK
The API mostly adheres to the PTC Mathcad Prime User Interface as a topology. PTC Mathcad Prime Applications typically start with the launching of PTC Mathcad Prime, then load a worksheet, set input variables (scalar, vector or matrix), and get result values (scalar, vector or matrix), save worksheets and close the application. All applications written in prior PTC Mathcad versions (PTC Mathcad 2001-PTC Mathcad 15) should be quickly adapted to the new API, it is very similar.
The SDK is sold and licensed per company. Purchase of the SDK and its associated Global Support gets the SDK *and* access to Technical Support for help writing applications interacting with the API.
