Ngmath example 1

Simple example of natural neighbor linear interpolation

This example can be created using HLU C and FORTRAN library calls or NCL. It demonstrates how to use the Natgrid package to do simple interpolation using natural neighbor interpolation (Natgrid is part of the Ngmath library). The names of the source files for this example are nm01c.c, nm01f.f, and nm01n.ncl.

Discussion

This module discusses how to use the Natgrid package using calls to the Ngmath library and the HLU library.

Creating the plot using HLUs

The HLU C program that generates this plot is called nm01c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called nm01f.f.

Creating the plot using NCL

The NCL script that generates this plot is called nm01n.ncl.

The data

This plot does not use any external data.

How to run this example

This example can be generated using a C program (nm01c.c), a FORTRAN program (nm01f.f), or an NCL script (nm01n.ncl). The examples are installed in the following locations:

You can copy this example and run it by typing "ng4ex nm01c", "ng4ex nm01f", or "ng4ex nm01n". A copy of the source file and resource file will be placed in your current working directory. The source code will be compiled and automatically run for you.
