BOOTSTRAP (klibm) functions


LIBRARY ROUTINE

kj1 - compute the Bessel function j1 of the argument.

LIBRARY CALL

double kj1(double x)

INPUT

OUTPUT

none

RETURN VALUE

the double precision value of the j1 Bessel function at x.

DESCRIPTION

The kj1 function computes an approximation of the j1 Bessel function. This function evaluates the Bessel function of the first kind integer order of the input argument x.

kj1 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 j1, otherwise kj1 is a macro to the Khoros portable version of j1.
