Hi, Im trying to put an image onto a push button. However, I seem to be missing something.
Heres my attempt.
Al=imread('LeftArrow.png');
a(:,:,1) = Al;
a(:,:,2) = Al;
a(:,:,3) = Al;
set(handles.pushbuttonLEFT,'CData',a)

Your png file is RGB, so Al is already 3 dimensional. When you try to assign the 3 dimensional array to the two dimensional array a(:,:,1) you are going to fail.

If you have the appropriate toolbox you can imresize() what you send into CData.
