scripts default iconDesign Pattern: Singleton (Creational) (Scripts) Publisher's description

Intent: Ensures a class only has one instance and provide a global point of access to it [1].

Intent: Ensures a class only has one instance and provide a global point of access to it [1].

Motivation: It's important for some classes to have exactly one instance. For example, it can be desirable to have only a single instance of a GUI. With a MATLABВ® GUIDE built GUI, the driver or main function provides a global point of access which is executed to,
1. initially instantiate the GUI; and
2. subsequently bring the existing GUI into focus *not* creating a new one.

Refer to the comments in 'Singleton.m' and 'SingletonImpl.m' for detail on the implementation. The script 'testSingletonImpl.m' demonstrates the use of 'SingletonImpl.m'. Further, a corresponding UML class diagram is illustrated in 'Singleton_UML_Diagram.pdf'.

Refer to pp.127-134 Gamma et al.[1] for more information on the Singleton Design Pattern.
