public class ElementwiseProduct
extends Object
implements VectorTransformer

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. param: scalingVec The values used to scale the reference vector's individual components.
