csdesign(varargin)

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