Template for Writing User 4 Functions in C-Plot

What is template.4.c?

      template_4.c is a fully functioning example for a C-Plot level 4 user function.  It uses C-Plot macros defined in p_funct.h which is included with C-Plot.  See ref1.4.c for an example.

    The program contains four functions:
1. setup(): Described in the C-Plot user manual
2. user4():
Described in the C-Plot user manual.  User 4 functions are only executed once, so the template iterates through the points (0 to npts).
3. myFunc(double x, double y):
The actual function goes here.  The example simply doubles the y value of the current C-Plot data.
4. initParam():
A parameter loading function.  This function is not necessary, but may be useful.  It reads the file template.dat  for the values of two arrays: P and C.  Instructions for creating and modifying a template file are included in template.dat and template_4.c.
