Local functions can be added anywhere in scripts and live scripts except within conditional contexts, such as if statements or for loops. Each local function must begin with its own function definition statement and end with the end keyword. For more information, see Add Functions to Scripts.

Functions contain one or more sequential commands and can accept inputs and return outputs. When you have multiple lines of code, use the function keyword to define a function within a file.

matlab支持函数重载，即可以创建具有相同名称但不同参数列表的多个函数。此外，matlab还支持可变参数列表，允许函数接收任意数量的参数。在matlab中，函数是执行特定任务的代码块，可以通过自定义函数来提高代码的可重用性和模块化。：matlab函数句柄是函数的引用，允许将函数作为参数传递给 ...

Functions are the basis of all scripting and programming languages. With functions, you can make your applications do anything you want. Functions are very useful and necessary in all applications that are design in MATLAB.
