what will be the output of the following code for JPEG image compression

thank you

but there is another problem in the coding for jpeg image compression.

r(p:q) = [y(1:i, j); eob]; %truncate trailing zeros, and add EOB,
           count= count + i + 1;   %and add to output vactor
           r((count+1):end) = [];    %delete unused portion of r
           y.size=uint16([xm xn]);
           y.numblocks = uint16(xb);
           y.quality = uint16(quality * 100);
           y.huffman = mat2huff(r);
   end

the error is :-

"Error in ==> Untitled
             y.huffman = mat2huff(r);"

You did not mention what the error is.

mat2huff is not a Mathworks routine. It appears you can get it here
