`pygslodeiv2 `_ provides a
`Python `_ binding to the
`Ordinary Differential Equation `_
integration routines exposed by the `odeiv2 interface `_ of
`GSL - GNU Scientific Library `_.
The odeiv2 interface allows a user to numerically integrate (systems of) differential equations.

The following `stepping functions `_ are available:

- rk2
- rk4
- rkf45
- rkck
- rk8pd
- rk1imp
- rk2imp
- rk4imp
- bsimp
- msadams
- msbdf

Note that all implicit steppers (those ending with "imp") and msbdf require a user supplied
callback for calculating the jacobian.

You may also want to know that you can use ``pygslodeiv2`` from
`pyodesys `_
which can e.g. derive the Jacobian analytically (using SymPy). ``pyodesys`` also provides
plotting functions, C++ code-generation and more.

Documentation
-------------
Autogenerated API documentation for latest stable release is found here:
``_
(and the development version for the current master branch are found here:
``_).

Installation
------------
Simplest way to install is to use the `conda package manager `_:

::

   $ conda install -c conda-forge pygslodeiv2 pytest
   $ python -m pytest --pyargs pygslodeiv2

tests should pass.

Binary distribution is available here:
``_, conda recipes for stable releases are available here: 
``_.

Source distribution is available here (requires GSL v1.16 or v2.1 shared lib with headers):
``_ (with mirrored files kept here:
``_)

Examples
--------
The classic van der Pol oscillator (see `examples/van_der_pol.py `_)

.. code:: python

   >>> import numpy as np
   >>> from pygslodeiv2 import integrate_predefined  # also: integrate_adaptive
   >>> mu = 1.0
   >>> def f(t, y, dydt):
   ...     dydt[0] = y[1]
   ...     dydt[1] = -y[0] + mu*y[1]*(1 - y[0]**2)
   ... 
   >>> def j(t, y, Jmat, dfdt):
   ...     Jmat[0, 0] = 0
   ...     Jmat[0, 1] = 1
   ...     Jmat[1, 0] = -1 -mu*2*y[1]*y[0]
   ...     Jmat[1, 1] = mu*(1 - y[0]**2)
   ...     dfdt[0] = 0
   ...     dfdt[1] = 0
   ...
   >>> y0 = [1, 0]; dt0=1e-8; t0=0.0; atol=1e-8; rtol=1e-8
   >>> tout = np.linspace(0, 10.0, 200)
   >>> yout, info = integrate_predefined(f, j, y0, tout, dt0, atol, rtol,
   ...                                   method='bsimp')  # Implicit Bulirsch-Stoer
   >>> import matplotlib.pyplot as plt
   >>> series = plt.plot(tout, yout)
   >>> plt.show()  # doctest: +SKIP
