public class ElementwiseProduct
extends UnaryTransformer<Vector,Vector,ElementwiseProduct>

:: Experimental :: Outputs the Hadamard product (i.e., the element-wise product) of each input vector with a provided "weight" vector. In other words, it scales each column of the dataset by a scalar multiplier.
