Examples of edu.ucla.sspace.vector.ScaledSparseDoubleVector

edu.ucla.sspace.vector.ScaledSparseDoubleVector
A decorator for {@link SparseDoubleVector}s that scales every value in a given {@link DoubleVector} by some non zero scale.
Note that this automatically computes the scaling of a {@link ScaledDoubleVector} so that backing vector is scaled only once, thuspreventing any recursive calls to scaling. @author Keith Stevens
