Rc() Function Rc ( X As  Double, Y As  Double, Optional Info As  Long  ) Carlson form of elliptic integral RC(x, y) Purpose This routine computes the Carlson form of elliptic integral RC(x, y). RC(x, y) = (1/2) * ∫ (t + x)^(-1/2)(t + y)^(-1) dt [0, ∞] For negative second argument y, rc computes the principal value. Returns Double Carlson form of elliptic integral RC(x, y). Parameters [in] X Argument x. (X >= 0) [in] Y Argument y. (Y <> 0) [out] Info (Optional) = 0: Successful exit. = -1: The argument X had an illegal value. (X < 0) = -2: The argument Y had an illegal value. (Y = 0) = 1: Floating point range error. Reference boost/math/special_functions
