BOOTSTRAP (klibm) functions


LIBRARY ROUTINE

kyn - compute the general Bessel function yn of the argument.

LIBRARY CALL

double kyn(int n, double x)

INPUT

OUTPUT

none

RETURN VALUE

the double precision value of the n-order Bessel function at x.

DESCRIPTION

The kyn function computes an approximation of the yn Bessel function. This function evaluates the Bessel function of the second kind of integer order n at the input argument x. The input argument x must be positive.

kyn is not a POSIX function, but is implemented in a few BSD math libraries. If it is implemented for the current architecture in libm.a, then this is simply a macro to yn, otherwise kyn is a macro to the Khoros portable version of yn.
