besknu() def besknu ( nu  , x    ) Modified Bessel function of the second kind of order ν Kν(x) (fractional order) Purpose besknu computes the modified Bessel function of the second kind of order ν Kν(x). Returns float Modified Bessel function of the second kind of order ν Kν(x). Parameters [in] nu Order ν. [in] x Argument x. (x > 0) Error handling If x < 0, domain error (EDOM) occurs. Range error (ERANGE) may occur. Reference boost/math/special_functions
