sbesinu() double sbesinu ( double  nu, double  x  ) Modified spherical Bessel function of the first kind of order ν iν(x) (fractional order) Purpose sbesinu computes the modified spherical Bessel function of the first kind of order ν iν(x). Returns Modified spherical Bessel function of the first kind of order ν iν(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
