_jnd() double _jnd ( double  u, double  k  ) Jacobi elliptic functions nd(u, k) Purpose jnd computes the Jacobi elliptic functions nd(u, k). The function is defined as follows: nd(u, k) = 1 / dn(u, k) Returns nd(u, k). Parameters [in] u Argument u. [in] k Argument k. Error handling Range error (ERANGE) may occur.
