dist1 {SpatialTools}

Calculate Euclidean distance matrix for a matrix of coordinates

Description

dist1 takes a matrix of coordinates and returns the Euclidean distance matrix of the coordinates. It does this using a compiled C program, so it is faster than the builtin R dist function.

Usage

dist1(coords)

Arguments

coords

An nr \times nc numeric matrix of coordinates.

Value

An nr \times nr matrix of Euclidean distances.
