nexted functions matlab in matlab

In MATLAB, you can define a function within another function. These are called nested functions.

Nested functions can access variables in their parent function workspace, even after the parent function has completed execution.

Here is an example of how to define and use a nested function in MATLAB:

main.m
function parentFunc(x)
    disp('This is the parent function')
    nestedFunc(x)
    
    function nestedFunc(y)
        disp('This is the nested function')
        disp(['The value of x is: ' num2str(x)])
        disp(['The value of y is: ' num2str(y)])
    end
end

In the example above, nestedFunc is defined within parentFunc. nestedFunc can access the input argument x of parentFunc even though parentFunc has completed execution.

You can call the parentFunc from the MATLAB command window and pass it an input argument:

main.m
>> parentFunc(5)
This is the parent function
This is the nested function
The value of x is: 5
The value of y is: 5

As you can see, the nested function nestedFunc was called from within parentFunc and it was able to access the variable x in the parent function.
