Wigner 6j-symbols. If physically inadmissible indices are supplied, a zero is returned. Order of elements:
/ j1 j2 j3 \
\ j4 j5 j6 /
Syntax
w=wigner_6j(j1,j2,j3,j4,j5,j6)
Parameters
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.
