在 MATLAB Online 中打开

1. The opening function:

handles.output = hObject;
filelist=dir(fullfile('C:\Users\Sonalika\Documents\MATLAB\test\*.jpg'));
handles.filelist = filelist;
handles.frameindex = 1;
% Update handles structure
guidata(hObject, handles);

2. pushbutton function:

function load_frame_Callback(hObject, eventdata, handles)
axes(handles.axes1);
filelist = handles.filelist;
frameindex  = handles.frameindex;
myfolder='C:\Users\Sonalika\Documents\MATLAB\test';
currentframefile = filelist(frameindex).name;
handles.frameindex = frameindex+1;
ff=fullfile(myfolder,currentframefile);
I=imread(ff);
imshow(I);
guidata(hObject, handles);

All the Best!

I agree that the list box is much more convenient, but since he asked that particular question let's give him that! My answer actually is not creating a list, its a function on the pushbutton so that every time you press it, it goes to next image. Just like he wanted. A similar func for decreasing has to be created.

I was actually doing this for my program but when I saw ur list suggestion I'm doing that instead. So you did help someone at least! Thanks! :)

Oh, you're right. I just saw the word list and I thought you had a listbox, but I can see that you actually don't because nowhere do you set the string property of a listbox control. You're just storing the whole list of filenames and the current "index" in fields attached to the global "handles" variable when you start up the program, and then using those in the "Next" and "Last" pushbutton callbacks.. That should work.

Not very easy to use or user friendly at all. Why not use a listbox like most programs, where the user can see the filenames and click on whatever file in whatever order they want, like in this framework : http://www.mathworks.com/matlabcentral/fileexchange/24224-magic-matlab-generic-imaging-component

is there any other alternative to view multiple images one by one.

Yes, you could use a popup that you loaded with all the filenames, just like you'd do with the listbox. Or you could use a push button and call uigetfile() to let the user browse every time. None are as user friendly as a listbox, but if you want to torture your users, you could use one of those methods.
