the real Wigner-d matrix d_l(beta) at one angle, or with bandwidth=L the list d_0 .. d_L; MATLAB’s Wigner_d_recursion

Syntax

d = wignerd(beta, l)

The (2l+1) x (2l+1) matrix of degree l.

ds = wignerd(beta, bandwidth=L)

The matrices of the degrees 0 to L.

Description

The matrices are those of MTEX’s Wigner blocks, indexed from -l to l, computed by a stable recursion over the degrees. Give either the degree or the bandwidth.

Input

beta one angle, the second Euler angle
degree the degree l

Keywords

keyword default description
bandwidth None the largest degree L of the list

Output

d ndarray of shape (2l+1, 2l+1)
ds list of the matrices of the degrees 0 to L
