j0
(), j0f
(),
j1
() and j1f
() compute the
Bessel function of the first kind of the order 0 and the
order 1, respectively, for the real value
x; the functions jn
() and
jnf
() compute the Bessel function of the
first kind of the integer order n for the real value
x.
The functions y0
(),
y0f
(), y1
() and
y1f
() compute the linearly independent
Bessel function of the second kind of the order 0 and the
order 1, respectively, for the positive
integer value x (expressed as a
double); the functions yn
() and
ynf
() compute the Bessel function of
the second kind for the integer order n for the
positive integer value x (expressed
as a double).
