Dear user i have a matlab code and text file for the above question but it shows some error ,please help me.
matlab code is ....
function varargout = pt(varargin)
% PT MATLAB code for pt.fig
% PT, by itself, creates a new PT or raises the existing
% singleton*.
%
% H = PT returns the handle to a new PT or the handle to
% the existing singleton*.
%
% PT('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in PT.M with the given input arguments.
%
% PT('Property','Value',...) creates a new PT or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before pt_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to pt_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

% See also: GUIDE, GUIDATA, GUIHANDLES
