a class representing an axis field on the sphere by harmonic series
Since an axis has no sign, not the axis itself but the six independent entries of the symmetric matrix v*v' are expanded into spherical harmonics. Evaluation recovers the axis as its leading eigenvector.
Syntax
aF = S2AxisFieldHarmonic(sF)
aF = S2AxisFieldHarmonic(fun)Input
| sF | 6x1 S2FunHarmonic, the entries xx, xy, yy, xz, yz, zz |
