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