Generates a double-centered matrix (row and column means are zero) from the weights of a distance matrix (see
weights_from_distance_matrix()) and a distance threshold. This is a required step before the computation of Moran's Eigenvector Maps.
double_center_distance_matrix ( distance.matrix = NULL, distance.threshold = 0 )
Distance matrix. Default:
Numeric, positive, in the range of values of
A double-centered matrix of the same dimensions as
