New functions are defined by selecting Tools: Fitting Function Organizer or Tools: Fitting Function Builder and clicking the New Function button. You can define and edit a function in Code Builder when Function Form = Origin C. When you click the button, to the right of the Function edit box, a special instance of the Code Builder workspace will open. Edit directly in this window, scrolling up to the very top, and adding #include directives for any NAG header files that you need.
The following tutorial demonstrates how to call a NAG function:
