calling subfunctions with handle

Hi! :)

I have funcntion with a subfunction containing a handle:

function h= tellsoner

x= 0;

h= @legg_til_soner;

function y= legg_til_soner;

x= x+1

y=x

end

end

% ......................I am wondering how I can call the subfunction to accumulate the values or am I supposed to call the parent function always..?

You can call a function from a function handle by appending parentheses to the end of the variable name, even if there are no input arguments.

fh = tellsoner;
out = fh()

x = 1

y = 1

out = 1

out = fh()

x = 2

y = 2

out = 2

out = fh()

x = 3

y = 3

out = 3

function h = tellsoner
x = 0;
h = @legg_til_soner;

    function y = legg_til_soner
        x = x+1
        y = x
    end

end
