computes an approximation from a given spherical function by computing the spherical Fourier coefficients with quadrature
Syntax
sF = S2FunHarmonic.approximate(f)
sF = S2FunHarmonic.approximate(f, 'bandwidth', bandwidth)Input
| f | function on the sphere (may be multidimensional) |
Options
| bandwidth | maximum degree of the spherical harmonics used to approximate the function |
