function varargout = psd(varargin)

% PSD MATLAB code for psd.fig

%      PSD, by itself, creates a new PSD or raises the existing

%      singleton*.

%

%      H = PSD returns the handle to a new PSD or the handle to

%      the existing singleton*.

%

%      PSD('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in PSD.M with the given input arguments.

%

%      PSD('Property','Value',...) creates a new PSD or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before psd_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to psd_OpeningFcn via varargin.

%

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one

%      instance to run (singleton)".
