distsuml2 and distsuml2gra at orloca package

Description

distsum and distsumgra functions for the Euclidean norm (l_2). Mainly for internal use.

Usage

distsuml2(o, x = 0, y = 0)

Arguments

o	An object of loca.p class.
x	The x coordinate of the point to be evaluated.
y	The y coordinate of the point to be evaluated.

Details

If (x,y) is a demand point partial=T means ignore such point to compute the gradient. This option is mainly for internal use.

Value

distsuml2 returns the objective function of the min-sum location problem, \sum_{a_i \in o} w_i d(a_i, (x,y)), where d(a_i, (x,y)) gives the euclidean distances between a_i and the point (x,y). distsumgra returns the gradient vector of the function distsum.
