DSP_export.m

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