BOOTSTRAP (klibm) functions


LIBRARY ROUTINE

kjn - compute the general Bessel function jn of the argument.

LIBRARY CALL

double kjn(int n, double x)

INPUT

OUTPUT

none

RETURN VALUE

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

DESCRIPTION

The kjn function computes an approximation of the jn Bessel function. This function evaluates the Bessel function of the first kind of integer n order of the input argument x.

kjn 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 jn, otherwise kjn is a macro to the Khoros portable version of jn.
