how to resolve varagout error

function varargout = untitled(varargin)
% UNTITLED M-file for untitled.fig
%      UNTITLED, by itself, creates a new UNTITLED or raises the existing
%      singleton*.
%
%      H = UNTITLED returns the handle to a new UNTITLED or the handle to
%      the existing singleton*.
%
%      UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in UNTITLED.M with the given input arguments.
%
%      UNTITLED('Property','Value',...) creates a new UNTITLED or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before untitled_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to untitled_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

*********************************************************************

there is an error in the code. Please help me out to resolve it. The error is attached herewith.Its urgent please help me out

[Sanjay Tiwari]

my email adress; [e-mail]

[Rik]

Please use the layout tools to make your code more readable.

GUIDE doesn't close functions with the end keyword. If you pasted a function where you did, the parsing will fail. Did you check if all functions in your file use the same convention?

[Sanjay Tiwari]

Sorry for the remarks in code. But the issue is not end kewords. I have deleted all the remarks and then try to run the program but the error remains same.

Yes i checked the function but i feel that function varagout is not defined. I have cheked other suggestion and i feel that varagout needs to be defined seperatly and it should be called in this program.

But i am unable to define this varaout. Please look into it.

[David Goodmanson]

Hi Sanjay, is that last line supposed to be just varargout = untitled(varargin) ?

[Sanjay Tiwari]

The last line is error which compiler was showing and it is" function varargout=untitled(varargin)". As said earlier i am unable to define the varargout.

[Walter Roberson]

You cannot define functions at the command line. You would need to store the above code in untitled.m

[Sanjay Tiwari]

agreed to your point.but if i will create the varargout function what should be the code

is it like this

function varargout = untitled(varargin)
    disp([' ' ]) % i dont know what to feed here
    disp([''])% etc
    
    for () = 1:nargout
        varargout{k} = k;
    end
end 

it this is wrong what could be if you can help me in this code

[Walter Roberson]

    for k = 1:nargout
        varargout{k} = k;
    end
    

    disp([' ' ]) % i dont know what to feed here
    disp([''])% etc
    

What did you want to output?

Answer 1

[Steven Lord]

It looks like you're trying to copy and paste that code into the Command Window. That's not going to work. As the error message states you will need to put that code in a file (as stated on this documentation page.) In this case, your file should end with the extension .m and its name needs to satisfy the same requirements as a valid variable name.

Once you've defined the function in the file and saved that file, call it.

[Sanjay Tiwari]

Thanks for the detailed response Steve. I slept at that time sorry for late response.

Well i have did the work again.

*********************************

function varargout = untitled(varargin)
for k = 1:nargout
varargout{k} = k;
    end

i saved this untitled.m (script) and then this programme (command wind)

error:

narargin not defined .

what is next ?????

I think that i could not clearly define my untitled script as well.

[Walter Roberson]

The code that you originally posted, the one that started with

function varargout = untitled(varargin)

What difficulty did you have when you stored that exact code in untitled.m ?

"narargin not defined ."

narargin is a mis-spelling of nargin .

However, nargin is only defined inside of functions, never in the command window. You should not be pasting any of that into the command window.

[Sanjay Tiwari]

Can you please help me with nargin function for this programme.

I tried to run with correct spelling and srcipt but i could not land on to somthing runing.

More over is untitled function is fine because compiler started with the first error or nargin i dont know when it will reach varargout.

[Steven Lord]

Show the full and exact text of the error message (include all the text displayed in red) and show the line on which the error occurs in your function (with four or five lines before and after that line, for context.) If the error occurs on line 10 of your function, for example, show us lines 5 through 15 using:

dbtype 5:15 untitled.m

Adjust the "5:15" part to reflect the actual line number from the error.

[Walter Roberson]

Please attach your current code and your .fig . Please do not post an image of code: attach the actual .m file

Please post a complete error message, together with a description of the actions needed to trigger the error.
