<p>This chapter describes functions for solving ordinary differential
equation (ODE) initial value problems.  The library provides a variety
of low-level methods, such as Runge-Kutta and Bulirsch-Stoer routines,
and higher-level components for adaptive step-size control. The
components can be combined by the user to achieve the desired
solution, with full access to any intermediate steps. A driver object
can be used as a high level wrapper for easy use of low level
functions.
</p>
<p>These functions are declared in the header file <samp>gsl_odeiv2.h</samp>.
This is a new interface in version 1.15 and uses the prefix
<code>gsl_odeiv2</code> for all functions.  It is recommended over the
previous <code>gsl_odeiv</code> implementation defined in <samp>gsl_odeiv.h</samp>
The old interface has been retained under the original name for
backwards compatibility.
