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.
|beta||second Euler angle|
|dlmin1,dlmin2||Wigner-d matrices of harmonic degree L-1 and L-2|
|dmn||Wigner d matrix d^L_(m,n)|
|or cell||array of all Wigner-d matrices up to harmonic degree L|
