BOOTSTRAP (klibm) functions


LIBRARY ROUTINE

ky1 - compute the Bessel function y1 of the argument.

LIBRARY CALL

double ky1(double x)

INPUT

OUTPUT

none

RETURN VALUE

the double precision value of the y1 Bessel function at x.

DESCRIPTION

The ky1 function computes an approximation of the y1 Bessel function. This function evaluates the Bessel function of the second kind of integer order at input argument x. The input argument must be positive.

ky1 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 y1, otherwise ky1 is a macro to the Khoros portable version of y1.
