frow_euc_dist: Fast Euclidean distance between rows of two matrics

In baruuum/btoolbox: random toolbox

Description

Fast Euclidean distance between rows of two matrics

Usage

frow_euc_dist(x, y, squared = FALSE)

Arguments

x	numeric matrix of dimension n times k
y	numeric matrix of dimension m times k
squared	boolean, if true the squared distance is returned

Details

This calculation should be much faster than using row_pdist. However, it is numerically less stable. Use at own risk.

Value

matrix of dimension n times m where the (i,j)th element is the Euclidean between the ith row of x and the jth row of y
