Examples of cc.redberry.core.context.NameAndStructureOfIndices

cc.redberry.core.context.NameAndStructureOfIndices
Container for structure of indices (see {@link cc.redberry.core.indices.StructureOfIndices}) of tensor and its string name. Two simple tensors are considered to have different mathematical nature if and only if their {@code IndicesTypeStructureAndName} are not equal. @author Dmitry Bolotin @author Stanislav Poslavsky @since 1.1
