WebHere, and throughout the remainder of §§ 10.47 – 10.60, n is a nonnegative integer. (This is in contrast to other treatments of spherical Bessel functions, including Abramowitz and Stegun (1964, Chapter 10), in which n can be any integer. However, there is a gain in symmetry, without any loss of generality in applications, on restricting n ≥ 0.)

Keyword Arguments: out ( Tensor, optional) – the output tensor. … WebThe spherical Bessel functions jn and yn have integer order and are implemented in the SciPy functions sph_jn and sph_yn. These SciPy functions are unusual in two ways: they return values of the functions up to and including the specified order, and they return derivative values as well. For example, sph_jn (2, 3.4) returns a pair of arrays.

WebHappily, the range of a given zero of the n'th spherical Bessel functions can be computed from the zeros of the (n-1)'th spherical Bessel function. Thus, the approach proposed here is recursive, knowing that the spherical Bessel function of order 0 is equal to sin (r)/r, whose zeros are well known.
