Ngmath example 16

Illustrates the use of csa2s and csa2xs.

This example can be created using NCL. It demonstrates how to use the Csagrid package to find an approximating cubic spline surface for two-dimensional input data, and to calculate the approximated second order mixed partial (Csagrid is part of the Ngmath library). The name of the source file for this example is nm16n.ncl.

Discussion

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

Creating the plot using HLU FORTRAN library calls

There is no HLU Fortran program version of this example.

Creating the plot using NCL

The NCL script that generates this plot is called nm16n.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 (nm16n.ncl). The example is installed in the following location:

You can copy this example and run it by typing "ng4ex nm16n". A copy of the source file and resource file will be placed in your current working directory and run through NCL for you.
