Though PTC Mathcad Prime has hundreds of built-in functions, you may find you also need to create your own. Use our built-in programming tool to create your custom utility functions. Save your utilities in a separate file, and include this file in your future worksheets for easy access to your utilities using "Include Worksheet".
This video features using Mathcad's programming tool to make row and column sum function for matrices, and then saving it in a utility functions worksheet, ending with including that utility functions worksheet into a new worksheet to allow for reuse.
Let us know in the comments section what kind of utility functions you use for your own worksheets!
You can use "Include Worksheet" only with the full version of PTC Mathcad Prime. Download it for 30 days at https://www.mathcad.com/trial
