# wigner_3j.m

Wigner 3j-symbols.

## Syntax

    w=wigner_3j(j1,m1,j2,m2,j3,m3)


## Description

If physically inadmissible indices are supplied, a zero is returned. Order of elements:

                         /j1 j2 j3\
\m1 m2 m3/


## Arguments

     j1-j3   - integers arranged in the order shown above

m1-m3   - integers arranged in the order shown above


## Outputs

    w       - the resulting 3j-symbol



## Notes

The function calls clebsch_gordan.m, which uses an arbitrary precision library. The output is numerically accurate to about j=10000.
