compute the Wigner d and Wigner D functions Note that for rot = pi/2 and high L the relative error of some matrix entries of the Wigner-d matrix increase rapidly. Moreover the matrix is no longer symmetric w.r.t. d(k,l)=d(-k,l).
Syntax
Dmn = Wigner_D(L,rot)
dmn = Wigner_D(L,beta)Input
| L | harmonic degree |
| rot | rotation |
| beta | second Euler angle |
Output
| Dmn | Wigner D matrix D_L^(m,n) |
| dmn | Wigner d matrix d_L^(m,n) |
