sq_dist: Calculates squared pairwise distances

In deepgp: Bayesian Deep Gaussian Processes using MCMC

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
