Cd = som_cldist(D,clinds1,clinds2,cldist,q,mask)
SOM_CLDIST Distances between two clusters.
Cd = som_cldist(Md,c1,c2,'single')
Cd = som_cldist(Md,c1,c2,'average')
Cd = som_cldist(Md,c1,c2,'complete')
Cd = som_cldist(Md,c1,c2,'neighf',H)
Cd = som_cldist(Md,c1,[],...)
Cd = som_cldist(D,c1,c2,'centroid',q,mask)
Cd = som_cldist(D,c1,c2,'ward',q,mask)
Cd = som_cldist(D,c1,[],...)
Input and output arguments ([]'s are optional):
D (matrix) size dlen x dim, the data set
(struct) map or data struct
Md (matrix) size dlen x dlen, mutual distance matrix, see SOM_MDIST
c1 (cell array) size n1 x 1, indices of clusters from which
the distances should be calculated, each cell
contains indices of vectors that belong to that
cluster (indices are between 1...dlen)
c2 (cell array) size n2 x 1, same as c1 but have the clusters
to which the distances should be calculated
(empty) c1 is used in place of c2
[q] (scalar) distance norm, default = 2
[mask] (vector) size dim x 1, the weighting mask, a vector of ones
by default
H (matrix) size dlen x dlen, neighborhood function values
Cd (matrix) size n1 x n2, distances between the clusters
