How do I fix this! I just started to learn about it

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

What is your question? Do you have any error?

[Nguyen Khac Thinh]

1.Reference to non-existent field 'axes1'.

2.Error in xulianh>pushbutton1_Callback (line 101)

axes(handles.axes1);

3.Error in gui_mainfcn (line 95)

feval(varargin{:});

4.Error in xulianh (line 42)

gui_mainfcn(gui_State, varargin{:});

5.Error in

matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)xulianh('pushbutton1_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback.

=)) i dont know. Can u help me, Sir?

[Guillaume]

Well, the error tells you all. You're trying to use the field axes1 from handle, but that field doesn't exist. Indeed it's never created in your code.

We can guess that it's supposed to be a handle to an axis in your figure but you never create such axis.

I'll repeat what I said in my answer. If you are a beginner in matlab, App Designer is much easier to work with than GUIDE.

[Nguyen Khac Thinh]

Thank you Sir, actually i want to try it in Matlab in advance, after that i will create a interface image processing by OpenCV, because i think, basically, their algorithm is the same between Matlab and Opencv. I will go back to the drawing board. Ff you don't mind, Please give me a contact address to receive your help in the future. Thank you once again.

Answer 1

[Guillaume]

If you are starting to learn matlab, then I would strongly recommend you learn to create GUIs using App designer instead of GUIDE (what you are using now). GUIDE is going to be deprecated soonish so learning it now might be a waste of time, and writing GUIs in app designer is a lot easier than with guide.

[Nguyen Khac Thinh]

Yah, thank you, Sir. i dont have more time to start from simple things. i try more everyday to complete my project in little time

Answer 2

[Steven Lord]

I suspect you tried to start your GUI by opening the figure file (double-clicking on it perhaps?) You need to start a GUIDE GUI by running the associated function (to initialize the GUI) not opening the figure file directly. Type the name of the function in the MATLAB Command Window and see if you still receive this error.
