elliptic_integral, a FORTRAN90 code which evaluates elliptic integral functions using Carlson's elliptic functions.
The complete and incomplete elliptic integrals of the first, second and third kind can be evaluated, with parameters A (angle in degrees), K (sine of A) or M (the modulus, K^2).
Routines are also supplied to evaluate Jacobi's elliptic functions CN, DN and SN.
