# wigner_6j.m

Wigner 6j-symbols.

## Syntax

    w=wigner_6j(j1,j2,j3,j4,j5,j6)


## Description

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

                   / j1 j2 j3 \
\ j4 j5 j6 /


## Arguments

    j1-j6   - integers arranged in the order shown above.


## Outputs

    w       - the resulting 6j-symbol



## Notes

The function calls wigner_3j.m, which calls clebsch_gordan.m, which uses an arbitrary precision library. The outpput is numerically accurate to about j=10000.
