Examples of cc.redberry.core.indices.IndicesBuilderSorted

cc.redberry.core.indices.IndicesBuilderSorted
This class provides functionality to construct {@code Indices} object bycombination other {@code Indices} objects. For example, if we have a product{@code X_mn*Y_ab} we can construct products indices by appendingconsequentially indices of tensor {@code X} and {@code Y} to{@code IndicesBuilderSorted}. As the result this class returns {@code SortedIndices}instance. @see Indices @author Dmitry Bolotin @author Stanislav Poslavsky
