I have a GUI with 5 axes in it, where images which are stored in text file(notepad) are displayed. Images in text file are not static, it keeps updating with new ones. I mean for first search images are different and after closing all windows again if i run same program for next search different images may get saved in notepad.
function displayResults(filename, header)
figure('Position',[200 100 700 400], 'MenuBar', 'none', 'Name', header, 'Resize', 'off', 'NumberTitle', 'off');
% Open 'filename' file... for reading...
fid = fopen(filename);
for N=1:5
imagename = fgetl(fid);
if ~ischar(imagename), break, end % Meaning: End of File...
(x) = imread(imagename);
axes(handles.axesN);
imshow(fname);
xlabel(imagename);
end
fclose(fid);
filename is text file
I need to fit these images on all 5 axes, but I'm getting error like undefined variable handles.axesN How can i go for it?

The question is not clear to me. You have posted the code 3 times now, but this does not increase the chance to understand it.

What do you expect "handles.axesN" to be? perhaps you want:
axes(handles.(sprintf('axes%d', N)));

Hi Guys, any update on this? I am having this same error. My code snippet below:
axes(handles.axesTagName);
imshow(theImage)

For his function displayResults(), handles was not passed in to the function so the function cannot see it. You'd need to pass in handles via the input argument list in order to use it inside the function.
handles is not a global variable that is automatically seen by all functions in the m-file, so if you want to use it, you must pass it in.

There are only 5, so get rid of the loop and just do it explicitly
% Read in image 1
theImage = imread(filename);
axes(handles.axes1);
imshow(theImage);
% Read in image 2
theImage = imread(filename);
axes(handles.axes2);
imshow(theImage);
and so on.
I suggest you use fullfile(), and exist(filename, 'file') to construct the full filename (folder + base filename + extension) and check to see that it actually exists.
