dist_cross: Cross distance matrix

In orthoDr: Semi-Parametric Dimension Reduction Models Using Orthogonality Constrained Optimization

Cross distance matrix

Description

Calculate the Gaussian kernel distance between rows of X1 and rows of X2. As a result, this is an extension to the stats::dist() function.

Usage

dist_cross(x1, x2)

Arguments

x1	First data matrix
x2	Second data matrix

Value

A distance matrix with its (i, j)th element being the Gaussian kernel distance between ith row of X1 jth row of X2.

Examples

# two matrices
set.seed(1)
x1 <- matrix(rnorm(10), 5, 2)
x2 <- matrix(rnorm(6), 3, 2)
dist_cross(x1, x2)
