MATLAB: Error while using imshow function.

imshow

%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)

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)

Douglas - perhaps try

imshow(logo_file_name, 'Parent', handles.axes3);

where you include the Parent name for the axes value.

Do not use eval(), especially not for this purpose.

[namafile, direktori] = uigetfile({'*.avi';'*.mov';'*.mp4';'*.mpeg'},'Buka Gambar')
if isequal(namafile,0)
  return;
end
filename = fullfile(direktori, namafile);
if ~exist(filename, 'file')
   warndlg( sprintf('Failed to find file "%s"', filename) ); %odd !
  return
end
I = imread(filename);
