The example (ex4.11) demonstrates how a fuzzy structure and sets can be managed with the given commands. The fuzzy tool includes only the commands needed to operate with a fuzzy set. In addition, you must use operations from a graphic structure if you would like to support working with fuzzy sets by a graphical presentation. Typically the fuzzy tool should hide these commands and thus only developers need to become familiar with them.
