sq_dist {deepgp}

Calculates squared pairwise distances

Description

Calculates squared pairwise euclidean distances using C.

Usage

sq_dist(X1, X2 = NULL)

Arguments

X1

matrix of input locations

X2

matrix of second input locations (if NULL, distance is calculated between X1 and itself)

Details

C code derived from the "laGP" package (Robert B Gramacy and Furong Sun).

Value

symmetric matrix of squared euclidean distances
