Strings help! URGENT!!!

Im having problems with this code, i am trying to reading ten image files, i then want to average the files as i have done. This part works.

However after doing this i want to output ten files of a string which contains the ten images after they have been averages so i can view them individually.

%reading all ten images
fileread = {'image001.png' 'image002.png' 'image003.png' 'image004.png' 'image005.png' 'image006.png' 'image007.png' 'image008.png' 'image009.png' 'image001.png'};
for i = 1:10
    fileread2{i} = sprintf('scan %.f', i);
end

% Input of a numerical threshold value

threshold = input('Enter a threshold value to estimate active bloodflow: ');

%determining whether the threshold value lies between the parameters
while threshold > 255 || threshold < 0
    disp('The threshold value is not a valid value')

      threshold = input('Enter a threshold value to estimate active bloodflow: ' );
  end

%Analysing images 1:10
pixels = zeros(1:10);

for i = 1:10
    images = imread(fileread{i});
    pixels(i) = length(find(images > threshold));
    fprintf('scan %s has %.f pixels above the threshold \n', fileread2{i}, pixels(i))
end

for i = 1:10
    images = images(1:10);
 for x = 2:199;
    for y = 2:199
            avg = [images(x-1, y-1:y+1); images(x, y-1:y+1); images(x+1, y-1:y+1)];
            images(x,y) = mean2(avg);

      end
   end
  end

Any assistance would be greatly appreciated...

pixels = zeros(1,10);  % pixels(1:10) will create a 10D array with 10! elements.

Same with images

To save the images for viewing use a cell array:

the_images = cell(10,1);
for ii = 1:10
 the_images{ii} = imread(...);
end
%to view image four
%imshow(the_images{4})

I think Sean meant:

pixels = zeros(1,10); %zeros(1:10) will create a 10D array with 10! elements

Thanks Walter. Note to self: don't log online prior to at least five gulps of coffee.
