computes an approximation from a given spherical vector field by computing the spherical Fourier coefficients with quadrature componentwise.
Syntax
sVF = S2VectorField.approximate(f)
sVF = S2VectorField.approximate(f, 'bandwidth', bw)Input
| f | S2VectorField, @function_handle in vector3d |
Output
| sVF | S2VectorFieldHarmonic |
Options
| bw | degree of the spherical harmonic (default: 128) |
