dist1: 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.

Examples

x <- matrix(rnorm(30), ncol = 3)
dist1(x)
