calculate a density function out of (weighted) unit vectors
Syntax
sF = calcDensity(v)
sF = calcDensity(v,'weights',w)
sF = calcDensity(v,'halfwidth',delta)
sF = calcDensity(v,'kernel',psi)
f = calcDensity(v,S2G)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 |
