let us consider following program for graphical user interface
function varargout = quadratic(varargin)
% QUADRATIC MATLAB code for quadratic.fig
% QUADRATIC, by itself, creates a new QUADRATIC or raises the existing
% singleton*.
%
% H = QUADRATIC returns the handle to a new QUADRATIC or the handle to
% the existing singleton*.
%
% QUADRATIC('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in QUADRATIC.M with the given input arguments.
%
% QUADRATIC('Property','Value',...) creates a new QUADRATIC or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before quadratic_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to quadratic_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

this program simple will allow to enter coefficients of quadratic equation and then solve equation and try to find roots,how can i take screenshot of GUI interface after this program?please help me,i want to save figure which occurs after running of this program,thanks in advance
