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.
