Function Handles

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 arguments to functions that evaluate mathematical expressions over a range of values.

Function handles can represent either named or anonymous functions. To create a function handle, use the @ operator. For example, create a handle to an anonymous function that evaluates the expression x² – y²:

f = @(x,y) (x.^2 - y.^2);
