amell
=====

Jacobi's am function



Calling Sequence
~~~~~~~~~~~~~~~~


::

    [sn]=amell(u,k)




Arguments
~~~~~~~~~

:u real scalar or vector
: :k scalar
: :sn real scalar or vector
:



Description
~~~~~~~~~~~

Computes Jacobi's elliptic function `am(u,k)` where `k` is the
parameter and `u` is the argument. If `u` is a vector `sn` is the
vector of the (element wise) computed values. Used in function `%sn`.
