org.apache.mahout.math.VectorIterable.times()
Return a new vector with cardinality equal to getNumRows() of this matrix which is the matrix product of the recipient and the argument @param v a vector with cardinality equal to getNumCols() of the recipient @return a new vector (typically a DenseVector) @throws CardinalityException if this.getNumRows() != v.size()
