gpuDist: Compute Distances Between Vectors on a GPU

Description Usage Arguments Value See Also Examples

View source: R/gpuHclust.R

Description

This function computes the distance between each vector of the 'points' argument using the metric specified by 'method'.

Usage

1
	gpuDist(points, method = "euclidean", p = 2.0)

Arguments

points

a matrix of floating point numbers in which each row is a vector in $R^n$ space where $n$ is ncol(points).

method

a string representing the name of the metric to use to calculate the distance between the vectors of 'points'. Currently supported values are: "binary", "canberra", "euclidean", "manhattan", "maximum", and "minkowski".

p

a floating point parameter for the Minkowski metric.

Value

a class of type "dist" containing floating point numbers representing the distances between vectors from the 'points' argument.
