Chapter Objectives This chapter discusses the object-oriented paradigm, including: Object-oriented programming (OOP) in general How MATLAB implements OOP This chapter is not intended as a full treatment of the art and science of object-oriented design and object-oriented programming (OOP). Rather, it presents some basic definitions of terms used in OOP and the implementation in MATLAB of some simple constructs. Subsequent chapters will extend these ideas to illustrate how dynamic data structures may be constructed and manipulated using OOP.

470 Chapter 18 Object-Oriented Programming 18.1 Object-Oriented Programming In Chapters 1–17 we saw MATLAB as a means for manipulating arrays sometimes in the guise of vectors or matrices, character strings, or cell arrays. Furthermore, the manipulation performed was conducted by writing scripts that sometimes call functions—either the functions built into MATLAB or functions we create ourselves. This type of programming is referred to as being in the procedural paradigm—functions and scripts as a form of procedure. This chapter considers a different paradigm altogether—the object- oriented (OO) paradigm. In this programming style, we still begin with a script, but the scripts that we write will usually create and interact with objects rather than arrays . 18.1.1 OO Background Languages that express the essential elements of the OO paradigm have been around since the 1960s when Simula was first developed. However, in the 1980s and 1990s, as massive software projects and especially graphical user interfaces (GUIs) became common, OO emerged as the paradigm of choice for designing and developing large software systems. Major software systems (like the various releases of Microsoft Windows) faced enormous design and integration challenges that could not be met by conventional programming practices. They needed language-imposed management of the interaction between large and small collections of programs and data. A secondary requirement in efficiently developing large software systems
