Multi-edit and condense a training set

    J = EDICON(D,NSETS,NITERS,NTRIES)

Input
 D Distance matrix dataset
 NSETS Number of subsets for editing, or [] for no editing (default: 3)
 NITERS Number of iterations for editing (default: 5)
 NTRIES Number of tries for condensing, or [] for no condensing (dflt: 10)
