Some General Purpose Utilities
##############################
These routines can be included individually; for example,
::

   # include <cppad/utility/vector.hpp>

only includes the definitions necessary for the ``CppAD::vector`` class.
They can also be included as a group, separate from the rest of CppAD, using
::

   # include <cppad/utility.hpp>

They will also be included, along with the rest of CppAD, using
::

   # include <cppad/cppad.hpp>

C++ Concepts
************
We refer to a the set of classes that satisfy certain conditions
as a C++ concept.
The following concepts are used by the CppAD Template library:

.. csv-table::
   :widths: auto

   NumericType,:ref:`NumericType-title`
   CheckNumericType,:ref:`CheckNumericType-title`
   SimpleVector,:ref:`SimpleVector-title`
   CheckSimpleVector,:ref:`CheckSimpleVector-title`

General Numerical Routines
**************************
The routines listed below are general purpose numerical routines
written with the floating point type a C++ template parameter.
This enables them to be used with algorithmic differentiation types,
as well as for other purposes.

.. csv-table::
   :widths: auto

   nan,:ref:`nan-title`
   pow_int,:ref:`pow_int-title`
   Poly,:ref:`Poly-title`
   lu_det_and_solve,:ref:`lu_det_and_solve-title`
   RombergOne,:ref:`RombergOne-title`
   RombergMul,:ref:`RombergMul-title`
   Runge45,:ref:`Runge45-title`
   Rosen34,:ref:`Rosen34-title`
   OdeErrControl,:ref:`OdeErrControl-title`
   OdeGear,:ref:`OdeGear-title`
   OdeGearControl,:ref:`OdeGearControl-title`

Miscellaneous
*************

Error Handler
=============
All of the routines in the CppAD namespace use the following
general purpose error handler:

The CppAD Vector Template Class
===============================
This is a simple implementation of a template vector class
(that is easy to view in a C++ debugger):
