MATLAB® and Its Applications in Engineering: [Based on MATLAB 7.5 (R2007b)]

8.6. Types of Functions

Functions can be classified into different categories based on their features and the manner in which they are applied. Some of them are as follows:

• Subfunctions

• Private function

• Nested function

• Inline function

8.6.1. Subfunctions

Function files can contain code for more than one function. The first function in the file is called primary function. The primary function is called by the name of the function M-file. Additional functions defined within the same file are called subfunctions. These functions are visible only to the primary function or other subfunctions defined in the same M-file. Each subfunction begins with its function definition line. These subfunctions follow each other and may occur in any order, as long ...
