Compute the square root of the Euclidean distances between latent positions and
return them with a negative sign.
Usage
lpz_dist(Z)
Arguments
Z
Latent positions matrix. The matrix size must be (n,k), where n and k denote respectively
the number of nodes in the network and the latent space dimensionality.
Value
Matrix containing the negative square root of the Euclidean distances between latent positions
