Matlab: Nested Functions

What Are Nested Functions?

A nested function is a function that is completely contained within a parent function. Any function in a program file can include a nested function.

For example, this function named parent contains a nested function named nestedfx:

1 2 3 4 5 6 7 8 9

function parent disp('This is the parent function') nestedfx function nestedfx disp('This is the nested function') end end

The primary difference between nested functions and other types of functions is that they can access and modify variables that are defined in their parent functions. As a result:

1. Nested functions can use variables that are not explicitly passed as input arguments.
2. In a parent function, you can create a handle to a nested function that contains the data necessary to run the nested function.
