calculate a density function out of (weighted) unit vectors
Syntax
Input
v | sampling points for density estimation vector3d |
S2G | vector3d |
w | weights, default is all one |
delta | halfwidth of the kernel, default is 10 degree |
psi | S2Kernel function, default is S2 de la Vallee Poussin |
Output
sF | S2Fun |
f | function values |
Options
halfwidth | halfwidth of a kernel |
kernel | specify a S2Kernel |
weights | vector of weights, with same length as v |
