Function Handles

Variables that allow you to invoke a function indirectly

A function handle is a data type that stores an association to a function. For example, you can use a function handle to construct anonymous functions or specify call back functions. Also, you can use a function handle to pass a function to another function, or call local functions from outside the main function.

To get started, see Create Function Handle.

Create Function Handle

Use a function handle to create an association to a named function or an anonymous function. Then, you can indirectly call the representative function.

Pass Function to Another Function

You can use function handles as input arguments to functions that evaluate mathematical expressions over a range of values, such as integral and fzero.

Parameterizing Functions

This topic explains how to store or access extra parameters for mathematical functions that you pass to functions such as fzero, ode45, or integral.

Call Local Functions Using Function Handles


Compare Function Handles

The result of comparing equality of function handles depends on what the handle represents and when you created it.
