I am 1st time making GUI in matlab... I need to display images. For this I have been using axes.. But image shown in axes is very small and it cannot reveal minor details... I want to display this image in a separate window, so that image can bee seen on full screen, (Like image shown by command figure,imshow(image))... And every time I press button, new image should replace the previous image, rather than opening in new window... Please show me ways of doing this..

You can set the 'InitialMagnification' property in imshow() to set an initial zoom level. Then you can call zoom() to adjust it further. I've posted code about zooming images either here or in the newsgroup. Search for "sldZoom" and see if you can find it.

Call the figure() command, but you'll still have to magnify the window somehow if you want to see that small minor details that you cannot see now.

newfig = figure();
newaxes = axes('Parent', newfig);
And to display or update the image,
image(YourArray, 'Parent', newaxes);

what is meant by this error??? :(
"??? Index exceeds matrix dimensions.
Error in ==> charGUI>LocateOD_Callback at 68
newaxes = handles.axes2('Parent', newfig);"
.................................................................
the piece of code that shows this error is
"newfig = figure();
newaxes = handles.axes2('Parent', newfig);
image(img_od, 'Parent', newaxes);"

I didn't say handles.axes2(), I said axes() . axes() creates a new axes. You need a new axes to go in the new figure.

"axes()" is the name of a special built-in function. It did not mean for you to substitute the actual name of your axes for it.
