Create a Continuous Random Variable with a von Mises distribution.

The density of the von Mises distribution is given by

.. math::
    f(x) := \frac{e^{\kappa\cos(x-\mu)}}{2\pi I_0(\kappa)}

with :math:`x \in [0,2\pi]`.

Parameters(more...)

        def VonMises(name, mu, k):

    Parameters
    ==========

    mu : Real number, measure of location
    k : Real number, measure of concentration

    Returns
    =======

    A RandomSymbol.

    >>> z = Symbol("z")

    >>> X = VonMises("x", mu, k)

    >>> D = density(X)(z)
    >>> pprint(D, use_unicode=False)
