calcDensity edit page

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 kernel function, default is de la Vallee Poussin

Output

sF S2Fun
f function values

Options

halfwidth halfwidth of a kernel
kernel specify a kernel
weights vector of weights, with same length as v
