Data_Extraction_Receiving_End.m

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