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