I already have one matrix of type [[a]] to store one image.
What I want to do is to devide the image into severial small blocks in same size.
To do that, I wrote this tool function.
chop :: Int -> [a] -> [[a]]
chop _  = 
chop n ls = take n ls : chop n (drop n ls)
But I do not know how to use it to write the function.
Thanks for any advice.
