org.grouplens.lenskit.vectors.MutableSparseVector.addScaled()
Add a vector to this vector with a scaling factor. It multiplies {@code v} bythe scaling factor {@code scale} and adds it to this vector. Only keys setin both {@code v} and {@code this} are modified. The scaling is doneon-the-fly; {@code v} is unmodified. @param v The vector to add to this vector. @param scale The scaling factor to be applied to the vector.


        MutableSparseVector v1 = MutableSparseVector.create(ts);
        v1.fill(0);
        v1.set(vec1);
        v1.multiply(1.0 / v1.norm());
        v1.addScaled(vec2, -1.0 / vec2.norm());


        distance = v1.norm();
        return 1-distance;
    }
