calcDensity

(method of vector3d)

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

param,val Parameters and values that control calcDensity
Parameter Description
'halfwidth'

halfwidth of a kernel

'kernel'

specify a kernel

'weights'

vector of weights, with same length as v

Output

sF

S2Fun

f

function values
