I am currently developing a basic image processing application on MATLAB. I have to implement undo to previous state feature. I searched net there is uiundo but it only undos GUI actions. Is there a simple command to undo. Thanks.
If you have plenty of memory to spare, you could store all of your program states in a structure and then push this structure into a circular buffer. The number of elements in the buffer would determine the number of levels of undo.
