Method Detail

sim

public double sim(DoubleVector v1,
         DoubleVector v2)

Returns the similarity between v1 and v2. If SimilarityFunction.isSymmetric() is false, the ordering does matter.

sim

public double sim(IntegerVector v1,
         IntegerVector v2)

Returns the similarity between v1 and v2. If SimilarityFunction.isSymmetric() is false, the ordering does matter.

sim

public double sim(Vector v1,
         Vector v2)

Returns the similarity between v1 and v2. If SimilarityFunction.isSymmetric() is false, the ordering does matter.
