WSbesi() Function WSbesi ( X As  Double, Nu As  Double, Optional Kode As  Long = 1  ) Modified spherical Bessel function of the first kind iν(x) (fractional order) Purpose WSbesi computes the modified spherical Bessel function of the first kind iν(x). Returns Modified spherical Bessel function of the first kind iν(x). Parameters [in] X Argument x. (X >= 0) [in] Nu Order ν. [in] Kode (Optional) Scaling option parameter. (default = 1) = 1: No scaling. (For other parameter values, the default value will be used except that Kode = 2 causes #VALUE! error)
