doubts regarding GUI. can some one explain me the code thats generated in each GUI? i hav given the code in the body.

    function varargout = compression(varargin)
    gui_Singleton = 1;
    gui_State = struct('gui_Name',       mfilename, ...
                       'gui_Singleton',  gui_Singleton, ...
                       'gui_OpeningFcn', @compression_OpeningFcn, ...
                       'gui_OutputFcn',  @compression_OutputFcn, ...
                       'gui_LayoutFcn',  [] , ...
                       'gui_Callback',   []);
    if nargin && ischar(varargin{1})
        gui_State.gui_Callback = str2func(varargin{1});
    end

    if nargout
        [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
    else
        gui_mainfcn(gui_State, varargin{:});
    end

Pradeep - what doubts do you have? The above code is typical for GUIs created using GUIDE and can be safely ignored. The important function is gui_mainfcn which (according to the documentation) handles GUI creation, layout, and callback dispatch.
