All Implemented Interfaces:

Transformation

public final class PowerUnfoldTransformation
extends java.lang.Object
implements Transformation

Expands all powers of products and powers with respect to specified variables and unwraps powers of indexed arguments into products (e.g. (A_m*A^m)**2 -> A_m*A^m*A_a*A^a).
