Clebsch-Gordan vector-coupling coefficients

v = clebschgordan(j1,j2,j,m1,m2,m)
v = clebschgordan(jm1,jm2,jm)
v = clebschgordan(j,m)

clebschgordan returns the value of a Clebsch-Gordan coefficient (also called vector addition or vector coupling coefficient), usually written in one of the forms

The six parameters can be specified separately or in groups. In the three-argument form, clebschgordan takes jm1 = [j1 m1] etc., if two arguments are given, it takes j = [j1 j2 j] and m = [m1 m2 m].

clebschgordan computes the Clebsch-Gordan coefficients via Wigner 3-j symbols

using the function wigner3j.
