Ngmath example 8

Illustrates the use of ftcurvp and ftcurvpi.

This example can be created using NCL. It demonstrates how to use the Fitgrid package to compute a periodic interpolatory spline under tension through a sequence of functional values (Fitgrid is part of the Ngmath library). Integrals of the interpolatory spline are also calculated. The name of the source file for this example is nm08n.ncl.

Discussion

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

Creating the plot using HLUs

Creating the plot using NCL

The NCL script that generates this plot is called nm08n.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 (nm08n.ncl). The example is installed in the following location:

  • $NCARG_ROOT/lib/ncarg/nclex/ngmath/nm08n.ncl
You can copy this example and run it by typing "ng4ex nm08n". A copy of the source file and resource file will be placed in your current working directory and run through NCL for you.
