Calculate the Distance Matrix Between Observed and Predicting Locations

Description

This function calculates the distance matrix between observed and predicting locations.

Usage

locUloc_R(loc, locp)

Arguments

loc

a matrix of n \times 2 which indicates the x-y coordinates of the observed locations; if a vector is used, it will be converted to matrix automatically

locp

a matrix of m \times 2 which indicates the x-y coordinates of the predicting locations; if a vector is used, it will be converted to matrix automatically

Details

This function performs the computation in R.

Value

A m \times n matrix with the element e_{ij} indicating the distance between the ith predicting location and the jth observed locations.
