computes a regularisation
Syntax
sF = S2FunHarmonic.regularisation(S2Grid,f,lambda)
sF = S2FunHarmonic.regularisation(S2Grid,f,lambda,'bandwidth',
bandwidth,'node_weights',W,'fourier_weights',What)Input
| S2Grid | grid on the sphere |
| f | function values on the grid (may be multidimensional) |
| lambda | parameter for regularisation |
Options
| bandwidth | maximum harmonic degree |
| W | weight w_n for the node nodes (default: Voronoi weights) |
| What | weight what_{m,l} for the Fourier space (default Sobolev weights for s = 2) |
