MATLAB: How to compare 2 rows with specific row gap

comparematrixrow

I have a matrix called myMatrix. In the below code I generated a 256 bit response by comparing ROW1 with ROW2, ROW3 with ROW4 etc.
How can I modify the code to generate a 256 bit response by comparing ROW1 with ROW17, ROW2 with ROW18 etc. 
output_bit=zeros(256,193);
for s=1:193;
    p=1;
for q=1:2:512; 
    
   if  myMatrix(q,s) > myMatrix(q+1,s);
        output_bit(p,s)=1;
   else 
       output_bit(p,s)=0;
       
   end
    p=p+1;
   
end 
end

Best Answer

In matlab loops are rarely needed and often make the code more complicated. Case in point, your original code comparing pairs of consecutive rows could be replaced by just:
output_bits = MyMatrix(1:2:end, :) > MyMatrix(2:2:end, :);
With your new question, what should happen after you've compared row 16 with row 32? Compare row 17 with row 33 or skip to comparing row 33 with row 49?
