I wrote this code and i would like to write a text on the top of this file and on the bottom. How can i do this?

      grayImage = imread('moon.tif');
[height, width] = size(grayImage)
[X, Y] = meshgrid(1:width, 1:height);
numberOfPixels = length(X(:))
points = [X(:) Y(:) grayImage(:)];
A = [X(:) Y(:) grayimage(:)];
fid = fopen('moon.txt','wt');
for ii = 1:size(A,1)
  fprintf(fid,'%g\t',A(ii,:));
  fprintf(fid,'\n');
end
fclose(fid)

Simply add a fprintf() before and after you write the gray levels to the text values.

fid = fopen('moon.txt','wt');
fprintf(fid,'Stuff at the beginning of the file.\n');
for ii = 1:size(A,1)
  fprintf(fid,'%g\t',A(ii,:));
  fprintf(fid,'\n');
end
fprintf(fid,'Stuff at the end of the file.\n');
fclose(fid)
