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
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 |
