regularisation edit page

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)
