DISTMATLATLON Computes distance matrix between list of coords in X and Y D = DISTMATLATLON(X,Y) for matrices X and Y, with columns [Lat Lon], returns the distance matrix where the (i,j)th entry is the distance between the i'th and j'th row of X and Y respectively. X and Y must have columns in the... Platforms: Matlab

D = DISTMAT(X,Y) for matrices X and Y returns the distance matrix where the (i,j)th entry is the d-norm distance between the ith and jth row of X and Y respectively.DISTMAT(X,Y,d) computes a specific d-norm distance.
