NAG DEFINITION CODE
and paste the following code below this line. Scroll up to go to line //add the header file for the NAG functions here.Define a new fitting function nag_integration_fitting in the new category as follow:Ĭlick the button beside the Function box to open the code builder then follow the steps below: Press F9 to open the Fitting Function Organizer and then create a new Category named FittingWithIntegral. The fitting procedure can be outlined into the following steps: Here, and are the model parameters we want to obtain from the data fitting.
Other sorts of persistent annoyance, e.g.: A nagging. Set up the Initial Code for the fitting function The notion that he forgot something nagged him the rest of the day.Create a fitting function with a Definite Integral using a NAG integration routine.Create a fitting function using the Fitting Function Organizer.Minimum Origin Version Required: Origin 8.0 SR6 What you will learn Note that an infinite NAG integrator is used here. It has a better performance compared to the built-in integration algorithm. For the current example, the NAG solution is recommended. There are built-in functions in Origin C which perform integration. You can call NAG functions to perform the integration while defining the fitting function. Origin allows user to define an Origin C fitting function which involves an integral. 3.2 Set the Initial Values for the Parameters or Setup the Initial Code.
