elliptic12i.m - function ELLIPTIC12i evaluates the Incomplete Elliptic Integrals of the First, Second Kind and Jacobi's Zeta Function for the complex value of phase U.

elliptic3.m - function ELLIPTIC3 evaluates incomplete elliptic integral of the third kind.

inversenomeq.m - function INVERSENOMEQ gives the value of Nome m = m(q).

jacobiThetaEta.m - function JACOBITHETAETA evaluates Jacobi's theta and eta functions.

nomeq.m - function NOMEQ gives the value of Nome q = q(m).
