euclidean: Euclidean distance matrice between points

In yingtliu/distPack: Evaluate distance matrice based on points in coordinates by different methods

Description

Computes the Euclidean distance between n points in m dimensions ,or two points with same dimensions.

Usage

euclidean(x, y, w = 1, output = "matrix")

Arguments

x	Numeric vector, or a matrix with size n x m.
y	(optional)Numeric vector; must be the same length as x. If no input of y, please specify all other parameters to avoid confusion.
w	Numeric value greater than 0, account for weight. Default is 1.
output	Format of output, either matrix or dist object. Default is matrix.

Value

Euclidean distance matrix or object calculated by sqrt(sum((x - y) ^ 2)) between points

Examples

euclidean(x = matrix(c(1, 2, 3, 4), 2, 2), output = "dist")

euclidean(rnorm(10), rnorm(10), w = 2)
