%sn(1)

NAME
%sn - Jacobi 's elliptic function

CALLING SEQUENCE
[y]=%sn(x,m)

PARAMETERS

x   : a point inside the fundamental rectangle defined by the elliptic integral; x is a vector of complex numbers

m   : parameter of the elliptic integral (0<m<1)

y   : result

DESCRIPTION
Jacobi 's sn elliptic function with parameter m: the inverse of the elliptic integral for the parameter m.

The amplitude am is computed in fortran and the addition formulas for elliptic functions are applied
