Please help me to understand, what processing is happening for the variable ' encoded_img ' in the following code

      post_fix=[];
      if find(encoded_img < 2, 1, 'last') < length(encoded_img)
          post_fix=encoded_img(find(encoded_img < 2, 1, 'last')+1:end);
      end
      pre_fix=encoded_img(1:3);
      encoded_img=encoded_img(4:find(encoded_img < 2, 1, 'last'));
      encoded_img_len=length(encoded_img)
      if mod(length(encoded_img),8) ~= 0
          encoded_img=[encoded_img, zeros(1, 8-mod(length(encoded_img),8))];
      end
      encoded_img_mat=reshape(encoded_img, 8, round(length(encoded_img)/8));
      uint8_encoded_img=bin2dec(num2str(encoded_img_mat'));

Can you not locate the author of this poorly documented code?

John D'Errico 2017-3-4

The thing is, code, without any documentation, taken out of context, where we have no clue what to expect, such code is almost impossible to just read and explain. And even if one could explain in theory what the code does in terms or processing pure numbers, it would not be an explanation that makes any sense to you.

So contact the author.
