scipy.special.ellipj¶
- scipy.special.ellipj(u, m) = <ufunc 'ellipj'>¶
Jacobian elliptic functions
Calculates the Jacobian elliptic functions of parameter m between 0 and 1, and real u.
Parameters: m, u
Parameters
Returns: sn, cn, dn, ph
The returned functions:
sn(u|m), cn(u|m), dn(u|m)
The value ph is such that if u = ellik(ph, m), then sn(u|m) = sin(ph) and cn(u|m) = cos(ph).
