locUloc: Calculate the Distance Matrix Between Observed and Predicting Locations

Description

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

Usage

locUloc(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

Value

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

Details

This function calls the underlying C++ program to do the computation.
