Installing a New Dynamical System in DsTool
</H1>
<P>
The addition of a new dynamical system in DsTool is a two-step process. The first
step entails writing a few procedures which define the set of governing equations for
the dynamical system (be it a vector field or a mapping) and the initial settings of
variables and parameters. If desired, additional procedures may be written which
define derivatives (with respect to space, time, and parameters) and define an
arbitrary number of auxiliary scalar-valued functions. The second step in the process
is to install the procedures into the libraries used to construct the executable
version of DsTool. To help you complete the necessary steps, we provide the following checklist:
<DL COMPACT>
<DT>1.
<DD>Define the dynamical system
<DL COMPACT>
<DT>(a)
<DD>Equations of motion
<DT>(b)
<DD>Derivatives
<DT>(c)
<DD>Inverse
<DT>(d)
<DD>Auxillary equations
<DT>(e)
<DD>Names and default ranges for variables
<DT>(f)
<DD>Names and default ranges for parameters
<DT>(g)
<DD>Names and default ranges for auxiliary functions
<DT>(h)
<DD>Periodic variables
<DT>(i)
<DD>Names of user-defined functions
</DL><DT>2.
<DD>Install the dynamical system
<DL COMPACT>
<DT>(a)
<DD>Initialization routine
<DT>(b)
<DD>Title
<DT>(c)
<DD>Compile source code
</DL></DL>
<P>
The discussion which follows contains details of this process and a description of the
files and variables involved. If you are not already there, change directories to
your local DsTool directory.
