[Numpy-discussion] no ordinary Bessel functions?

When I issue the command
np.lookfor('bessel')
I get the following:
Search results for 'bessel'
---------------------------
numpy.i0
Modified Bessel function of the first kind, order 0.
numpy.kaiser
Return the Kaiser window.
numpy.random.vonmises
Draw samples from a von Mises distribution.
I assume that there is an ordinary (unmodified) Bessel function in NumPy,
but have not been able to figure out how to access it. Also, I need to
operate sometimes on scalars, and sometimes on arrays. For operations on
scalars, are the NumPy Bessel functions significantly slower than the SciPy
Bessel functions?
