Features:-

The software industry has evolved considerably since the early 1990s, when MATLAB^® object-oriented programming features were first developed. For example, design patterns using objects are now commonplace. Over the intervening years, MathWorks developers have learned a great deal about how programmers use objects and what capabilities they require.

A key goal in updating the object-oriented programming capabilities of MATLAB in R2008a was to apply some of these lessons while remaining true to three core principles of the MATLAB language: the centrality of arrays and array indexing, the importance of mathematical functions, and the use of multiple named input and output parameters.

For experienced object-oriented programmers, this article explains the rationale behind some of the MATLAB design decisions in R2008a, including why MATLAB object-oriented features differ in significant ways from other popular object-oriented languages. In particular, this article examines methods and parameters, inheritance, handles, properties, and object lifecycle management.

Methods and Parameters

In R2008a, MATLAB preserves the method-definition, calling, and dispatching semantics of earlier versions of MATLAB. This means that objects are explicit parameters to the methods that act on them. Unlike many object-oriented languages, in MATLAB the array, or matrix, takes center stage. There is no special type for arrays, and all classes inherently support arrays. Moreover, because MATLAB methods frequently need to act on multiple objects, symmetry among multiple object parameters is more important in MATLAB code. For example, in MATLAB, plus is implemented with

function C = plus(A, B)

Inside the method, A, B, and C are all variables that can be given names appropriate to the context and used as variables might be used in mathematical equations. After all, methods are simply functions that act on objects. The only characteristic unique to methods is that they have access to the internals (the protected and private definitions) of the class. In MATLAB, there are no implicit parameters to methods.

Why is there no implicit "this" object in MATLAB?

In some languages, one object parameter to a method is always implicit. In such languages, a method always acts on a single scalar object without any need to access elements of an object array. Consider a MATLAB method that acts on an object array:

function S = sum(X)
  S = 0;
  for k = 1:length(X)
    S = S + X(k).Value;
  end
end

While languages with an implicit object parameter provide a "this" keyword to access the implicit object, they usually do not require you to access a property through "this". If MATLAB had implicit properties, the logical extension to array-based objects would be to index into nothing:

S = S + (k).Value;

Inheritance

In R2008a, MATLAB introduces a new inheritance model based on the idea that a class defines a set of objects with common traits and behaviors. A subclass defines both a subset of objects that exhibit the traits and behaviors defined by the superclass and additional traits and behaviors not exhibited by all instances of the superclass. Before R2008a, the fact that MATLAB objects were implemented using struct arrays was highly visible and central to the way classes inherited from other classes. An object belonging to a subclass was a struct that contained a field for each superclass, and that field contained an object belonging to the superclass.

This approach is, in many ways, simple and elegant. For example, it is easy to construct subclass instances using superclass constructors without special syntax, and it is easy to call superclass methods from subclass methods—you simply call the method on the superclass object contained by the subclass. However, there were problems with this model of inheritance.

One deficiency with the pre-R2008a inheritance model was that a superclass method could be called from a subclass method only by passing the superclass component of the object. This meant that the superclass method did not receive the whole object, and calls made by the superclass method would not dispatch to the subclass.
