Maybe it's due to you looking for the wrong extension in the folder. For example, maybe this:

addpath('C:\Users\User\Desktop\LIVE database\databaserelease2\jpeg');
for i=1:233
    A=imread(sprintf('img%d.bmp',i));
    A1=rgb2gray(A);
    A2=double(A1);
    FYPdatabase{575+i,1}=A2;
    FYPdatabase{i,3}=1;
end

should really be this:

folder = 'C:\Users\User\Desktop\LIVE database\databaserelease2\jpeg';
filePattern = fullfile(folder, '*.jpeg')
fileList = dir(filePattern)
for k = 1 : numel(fileList) % For however many files are there...
	% Get the full filename.
	fullFileName = fullfile(fileList(k).folder, fileList(k).name);
	fprintf('Adding %s\n', fullFileName)
	% Read in original image.
	rgbImage = imread(fullFileName);
	% Convert from color to grayscale if necessary.
	if size(rgbImage, 3) == 3
		% It's color.  Need to convert to gray scale.
		grayImage = rgb2gray(rgbImage);
	else
		grayImage = rgbImage; % It's already grayscale.
	end
	grayImage = double(grayImage);
	% Add it to the cell array.
	% 575 should be a variable that adjusts according to how many
	% images there were in the prior loops!!!
	FYPdatabase{575 + k, 1} = grayImage;
	FYPdatabase{k, 2} = []; % 2 is unassigned for some reason???
	FYPdatabase{k, 3} = 1;
end

This is more robust than what you have. Make similar adjustments for the other loops that handle other image file extensions.

thnks. but still didnt get
