I made a GUI that allows the user to determine regions in an image by using ROI object. the ROI object return its position as a matrix. I want to save the positions in a cell array when ever the user determine region in the image.
How can I do that?

An example:
A = {rand(4)} %stores the matrix as a cell array if you use curly braces
you can access the elements like a normal one
A{1}(1,1) %first element is obtained

@sara sar: if you want to pass data between callback function then use guidata (if you are unfortunately using GUIDE) or use nested functions (if you are happily writing your own GUI):
Note that callback functions do not return any output arguments, so there is no point in defining varargout.
If you want to return data from the GUI to the base workspace then either follow what I explained in my last comment, or if you are using GUIDE then use the OutputFcn:
Note that you can use waitfor inside the OutputFcn.

You don't need a cell array. See attached demo.
The best way to save the coordinates of a segmented image is as a binary image, or as boundaries (after using bwboundaries()).
You can use imwrite() to save the binary image in a .PNG disk file, or use save() to save the boundaries in a .mat file on disk if you need to.
