Can anyone Help me with the Errors in this code? It's about Face Recognition using Eigenfaces

function varargout = FaceRec(varargin)
gui_Singleton =1;
gui_State = struct('gui_Name'       mfilename, ...
                   'gui_Singleton', gui_Singleton; ...
                   'gui_OpeningFcn' @FaceRec_OpeningFcn, ...
                   'gui_OutputFcn'  @FaceRec_OutputFcn, ...
                   'gui_LayoutFcn'  [] , ...
                   'gui_Callback',  []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end;

You have

gui_State = struct('gui_Name'       mfilename, ...
                 'gui_Singleton', gui_Singleton; ...
                 'gui_OpeningFcn' @FaceRec_OpeningFcn, ...
                 'gui_OutputFcn'  @FaceRec_OutputFcn, ...
                 'gui_LayoutFcn'  [] , ...
                 'gui_Callback',  []);

You need commas between all of the parts, and the semi-colon needs to be a comma

gui_State = struct('gui_Name',       mfilename, ...
                 'gui_Singleton', gui_Singleton, ...
                 'gui_OpeningFcn', @FaceRec_OpeningFcn, ...
                 'gui_OutputFcn',  @FaceRec_OutputFcn, ...
                 'gui_LayoutFcn',  [] , ...
                 'gui_Callback',  []);

You have

    [filename, pathname] = uigetfile ('*.jpg',Load Image');

You are missing the opening ' for the second string

    [filename, pathname] = uigetfile ('*.jpg','Load Image');

You have

eval('img==imread(str);');

That asks to compare img to the result of imread(). That is a problem because img is probably not defined at that point. But it might be defined, depending on exactly which variables were in the two .mat that you load()'d.

You should probably change that to

img = imread(str);

Warning: the files you are trying to read might not be in the current directory...

You have

cpy=imagesc(ReshapedImage);

That leaves cpy as being the handle to an image() object that is displaying that image.

You have

      if(img==cpy)

but it looks like img is intended to be the result of reading the file in as data. The image data is never going to equal the graphics handle. I do not know what you were trying to do there.

Changed to img = imread(str); but still there is error
