dist-vclMatrix: GPU Distance Matrix Computations

In cdeterman/gpuR: GPU Functions for R Objects

Description

This function computes and returns the distance matrix computed by using the specified distance measure to compute the distances between the rows of a data matrix.

Usage

distance(x, y, method = "euclidean")

## S4 method for signature 'vclMatrix'
dist(x, method = "euclidean", diag = FALSE,
  upper = FALSE, p = 2)

## S4 method for signature 'vclMatrix,vclMatrix'
distance(x, y, method = "euclidean")

## S4 method for signature 'gpuMatrix'
dist(x, method = "euclidean", diag = FALSE,
  upper = FALSE, p = 2)

## S4 method for signature 'gpuMatrix,gpuMatrix'
distance(x, y, method = "euclidean")

Arguments

x	A gpuMatrix or vclMatrix object
y	A gpuMatrix or vclMatrix object
method	the distance measure to be used. This must be one of "euclidean" or "sqEuclidean".
diag	logical value indicating whether the diagonal of the distance matrix should be printed
upper	logical value indicating whether the upper triangle of the distance matrix
p	The power of the Minkowski distance (not currently used)

Value

a gpuMatrix/vclMatrix containing the corresponding distances
