gegenbauerd() double gegenbauerd ( unsigned int  n, double  lambda, double  x, unsigned int  k  ) k-th derivative of Gegenbauer polynomial Cn(λ)(x) Purpose This function computes the k-th derivative of the Gegenbauer polynomial. Returns k-th derivative of Gegenbauer polynomial Cn(λ)(x). Parameters [in] n Degree of polynomial n. (n >= 0) [in] lambda Parameter λ. [in] x Argument x. [in] k Computes the k-th derivative. (k >= 1) Error handling Range error (ERANGE) may be reported. Reference boost/math/special_functions
