Defining Labels and Initial Conditions
</H2>
This section explains how to complete the definition of a dynamical
system by giving DsTool information about the structure of phase space,
the names of variables, and initial conditions.
<P>
This section is split into subsections. The subsections describe how to provide
information on variables, parameters, auxiliary functions, periodic variables,
and numerical algorithms.
<P>
Before we begin,
find the code segment of bball_def.c which looks like
<PRE>
/* ------------------------------------------------------------------------
Procedure to define default data for the dynamical system. NOTE: You
may change the entries for each variable but DO NOT change the list of
items. If a variable is unused, NULL or zero the entry, as appropriate.
------------------------------------------------------------------------ */
int user_init()
{
/* ------------ define the dynamical system in this segment --------------- */
...
</PRE>
and change the name of the function from user_init() to bball_init().
