Ngmath example 9

Illustrates the use of ftcurvs and ftcurvps.

This example can be created using NCL. It demonstrates how to use the Fitgrid package to calculate a smoothing spline under tension for a non-periodic function as well as for a periodic function (Fitgrid is part of the Ngmath library). The name of the source file for this example is nm09n.ncl.

Discussion

This module discusses how to use the Fitgrid package from within NCL.

Creating the plot using NCL

The NCL script that generates this plot is called nm09n.ncl.

The data

This plot does not use any external data.

How to run this example

This example can be generated using an NCL script (nm09n.ncl). The example is installed in the following location:

  • $NCARG_ROOT/lib/ncarg/nclex/ngmath/nm09n.ncl
You can copy this example and run it by typing "ng4ex nm09n". A copy of the source file and resource file will be placed in your current working directory and run through NCL for you.
