Gegenbauerd_sub() Sub Gegenbauerd_sub ( Ret As  Double, N As  Long, Lambda As  Double, X As  Double, K As  Long, Optional Info As  Long  ) K-th derivative of Gegenbauer polynomial Cn(λ)(x) (Subroutine version) Purpose Computes the k-th derivative of the Gegenbauer polynomial. Parameters [out] Ret The k-th derivative of Gegenbauer polynomial Cn(λ)(x). [in] N Degree of polynomial n. (N >= 0) [in] Lambda Parameter λ. [in] X Argument x. [in] K Computes the K-th derivative. (K >= 0) [out] Info (Optional) = 0: Successful exit. = -1: The argument N had an illegal value. (N < 0) = -4: The argument K had an illegal value. (K < 0) = 1: Floating point range error.
