Method Detail

squaredDistance

public static double squaredDistance(DistanceMatrix mat1,
                                     DistanceMatrix mat2,
                                     boolean weighted)

compute squared distance to second distance matrix. If both matrices have the same size it is assumed that the order of the taxa is identical.

minus

public static DistanceMatrix minus(DistanceMatrix parent,
                                   int taxaToRemove)

Returns a distance matrix with the specified taxa removed.
