cos_dis: Cosine distance matrice between points

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

Description

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

Usage

cos_dis(x, y, 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.
output	Format of output, either matrix or dist object. Default is matrix.

Value

Cosine distance matrix or object calculated by 1 - dot(x, y) / (norm(x) * norm(y)) between points

Examples

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

cos_dis(rnorm(10), rnorm(10))
