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