Hi, of what ? Of an analytical known function ? Sum[a[l,m]*SphericalHarmonicY[l,m,th,phi],{l,0,Infinity},{m,-l,l}] with a[l,m]=Integrate[ Conjugate[SphericalHarmonicY[l,m,th,phi]]f[th,phi]*Sin[th], {th,0,Pi},{phi,0,2Pi} ] Regards Jens Alex S wrote: > > hello dear everybody, > how to calculate Spherical Harmonic expansion Coefficients? > I am looking for an algorithm possibly for mathematica. > please help > thanks, > A
