L2normalizeFourierCoefficients edit page

Since MTEX version 5.9 we use L2 normalized Wigner-D functions as basis functions for the harmonic series expansion of ODFs/SO3Funs.

Up to MTEX version 5.8 the ODFs has been definded by F(R)=ˆfk,lnDk,ln(R) with Dk,ln(R(α,β,γ))=eikγdk,ln(cosβ)eilα. Hence the L2 norm of the Wigner-D function Dk,ln was 2n+1.

Now since MTEX version 5.9 the Wigner-D functions have L2 norm 1. Hence they are defined by Dk,ln(R(α,β,γ))=2n+1eikγdk,ln(cosβ)eilα.

Take a look at Wigner-D functions.
