Class EliminateDueSymmetriesTransformation

java.lang.Object

cc.redberry.core.transformations.EliminateDueSymmetriesTransformation

All Implemented Interfaces:

Transformation

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

Removes terms from tensor, which are zero because of their symmetries. For example, if A_mn is symmetric and B^mn is antisymmetric, then A_mn*B^mn is zero.

Since:

1.0
