The body of a function can include valid MATLAB expressions, control flow statements, comments, blank lines, and nested functions. Any variables that you create within a function are stored within a …

This MATLAB function declares a function named myfun that accepts inputs x1,...,xM and returns outputs y1,...,yN.

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.

The at symbol (@) creates handles to anonymous and named functions, and is also used to call superclass methods from within a subclass. For instance, f = @(x,y) x+y creates an anonymous …

This topic explains the term local function, and shows how to create and use local functions. MATLAB ® program files can contain code for more than one function.

Use a function handle to create an association to a named function or an anonymous function.

Add functions to scripts to reuse code within a script and avoid creating and managing separate function files.

You can create an anonymous function that returns multiple outputs using the deal function. See Return Multiple Outputs from Anonymous Function for an example.

For example, create a function in a file named makeParabola.m. This function accepts several polynomial coefficients, and returns a handle to a nested function that calculates the value of that …

A function handle is a MATLAB ® data type that represents a function. A typical use of function handles is to pass a function to another function. For example, you can use function handles as input …
