Compute Wigner-d matrices by recursion formula. Therefore it is possible to generate a Wigner-d matrix by input of the two Wigner-d matrices with next smaller harmonic degree. It is also possible to calculate all Wigner-d matrices up to given harmonc degree L.
Syntax
dmn = Wigner_d_recursion(dlmin1,dlmin2,beta)
dmn = Wigner_d_recursion(dlmin1,dlmin2,beta,'half')
dmn = Wigner_d_recursion(L,beta)Input
| L | harmonic degree |
| beta | second Euler angle |
| dlmin1,dlmin2 | Wigner-d matrices of harmonic degree L-1 and L-2 |
Output
| dmn | Wigner d matrix d^L_(m,n) |
| or cell | array of all Wigner-d matrices up to harmonic degree L |
