MATLAB Object-Oriented Programming

Class Method to Implement Description

size Determine the dimensions of an array

See “Use of size and numel with Classes” on page

12-77

subsindex Support using an object in indexing expressions

See “Objects in Index Expressions” on page 17-

37

Saving and Loading Objects

loadobj and saveobj Customize behavior when loading and saving

objects

See “Object Save and Load”

Reshape and Rearrange

permute Rearrange dimensions of N-D array

transpose Transpose vector or matrix

ctranspose Complex conjugate transpose

reshape Reshape array

Determine Size and Shape

isscalar Determine if the input is a scalar

isvector Determine if the input is a vector

ismatrix Determine if the input is a matrix

isempty Determine if the input is empty

Overload Functions and Override Methods

Overloading and overriding are terms that describe techniques for customizing class

behavior. Here is how we use these terms in MATLAB.

Overloading

Overloading means that there is more than one function or method having the same name

within the same scope. MATLAB dispatches to a particular function or method based on

the dominant argument. For example, the timeseries class overloads the MATLAB plot
