Calculate Euclidean distance matrix between coordinates of two matrices
dist2 takes the matrices of coordinates
coords1 and coords2 and returns the
inter-Euclidean distances between coordinates.
dist2(coords1, coords2)
coords1 |
An nr1 \times nc1 numeric matrix of coordinates. |
coords2 |
An nr2 \times nc2 numeric matrix of coordinates. |
An nr1 \times nr2 matrix of Euclidean distances.

x1 <- matrix(rnorm(30), ncol = 3) x2 <- matrix(rnorm(60), ncol = 3) dist2(x1, x2)
