error while using imshow function.

%I have an empty "axes1" in GUI. I also have an picture in C directory. I want that while fig file opens, this picture can be automatically embed into this axes1. I wrote this code but it fails.

%filename=logo.png

imshow(logo, 'Parent', handles.axes1)

 % I wrote this code at the end of my function (% --- Executes just before  my_guide_name is made visible.

function my_guide_name_OpeningFcn(hObject, eventdata, handles, varargin)

It would be better if you can specify the error you are getting.

Attempt to execute SCRIPT logo as a function:

C:\Program Files\MATLAB\R2012a\toolbox\matlab\general\logo.m

Error in bursa_wolf>bursa_wolf_OpeningFcn (line 49)

imshow(logo, 'Parent', handles.axes1)

Error in gui_mainfcn (line 221)

    feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure),

 varargin{:});

Error in bursa_wolf (line 42)

    gui_mainfcn(gui_State, varargin{:});

You should specify full image name(extension too ) within singles quotes. You are getting this error because logo is a predefined command in MATLAB. so you must enclose the name in quotes: 'logo.png'

Moreover,if your image is in directory other than your work directory you should move the image in your work directory or you can use imread to read that image:

I = imread('pathName\fileName');
imshow(I)

I changed the name, My file name=neu.png. Directory is the same to Matlab. This time my code is;

imshow(neu, 'Parent', handles.axes1)

%it gives this error this time;

Undefined function or variable 'neu'.

Error in bursa_wolf>bursa_wolf_OpeningFcn (line 49)

imshow(neu, 'Parent', handles.axes1)

Error in gui_mainfcn (line 221)

    feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure),
 varargin{:});

Error in bursa_wolf (line 42)

    gui_mainfcn(gui_State, varargin{:});

I told you to enclose the name in single quotes:

imshow('neu.png', 'Parent', handles.axes1)

Hello, can i ask u? what's the problem with this?

Error: File: imshow.m Line: 677 Column: 1

The function "adjustXYData" was closed with an

'end', but at least one other function definition

was not. To avoid confusion when using nested

functions, it is illegal to use both conventions in

the same file.
