t i am not getting rid of following errors(attached updated file)
??? Reference to non-existent field 'result'.
Error in ==> test1>pushbutton1_Callback at 151 set(handles.result,'String',total_matched_percentage);
Error in ==> gui_mainfcn at 96 feval(varargin{:});
Error in ==> test1 at 41 gui_mainfcn(gui_State, varargin{:});
Error in ==> @(hObject,eventdata)test1('pushbutton1_Callback',hObject,eventdata,guidata(hObject))

Your code does not create handles.result so it is only going to exist if it is in your .fig file. If you were to post your .fig file then someone could check it.

The .m file is a modification of a project "Image Processing based Intelligent Traffic Control Systems (IPITCS)" developed by Amber Deep Singh, Abdul Hadi Parwana and Kamran Shahid Baig, the original code for which is at http://www.slideshare.net/louiseantonio58/image-processing-based-intelligent-traffic-control-systemmatlab-gui . You would need to get their .fig file to use that code. However, since you are developing your own code for your own academic project and are being very careful to avoid plagiarism, you do not need their code: you only need to study their techniques so that you can implement your own code.

The code in that .m file is so poor that you would not want to model yours after it anyway. You'd be better off reading this and then coding it up yourself.

Good evening sir, i m doing project under double encryption based method fuzzy vault method for finger print identification. i m getting error in this code like "gui_mainfcn(gui_State, varargin{:});" can you please help me.
thank you sir
function varargout = gui_final(varargin)
% GUI_FINAL M-file for gui_final.fig
% GUI_FINAL, by itself, creates a new GUI_FINAL or raises the existing
% singleton*.
%
% H = GUI_FINAL returns the handle to a new GUI_FINAL or the handle to
% the existing singleton*.
%
% GUI_FINAL('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in GUI_FINAL.M with the given input arguments.

I'm also getting the same error during my GUI to conversion of (C code) generation. Does anyone know how to rectify it?
