function [hNest,hLocal] = functionsExample(v)
hNest = @nestFunction;
hLocal = @localFunction;
    function y = nestFunction(x)
        y = x + v;
    end
end
function y = localFunction(z)
y = z + 1;
end

This is some code. What is the problem? Do you get an error message? If so, which one? When does the message appear, or in other words: how do you call this function?

在 MATLAB Online 中打开

test6.m

It ran for me with no errors.

Note that you never actually call either nestFunction() or localFunction(). You just assign function handles and exit. So, they never actually use your x, y, v, or z variables. Just leave off the semicolon when you call

[hNest,hLocal] = functionsExample(5)

or set a break point in those functions to verify that fact.

@Aravind Mallemputi, good. My guess is that you just posted some simplified, dummy code that was not what you actually were running. And then you realized that you needed to call the internal, nexted functions -- they do not automatically call themselves. If I helped you, you can "Accept" or Vote for this answer.
