Saving output results in a for loop

Hello, I am trying to make a loop that will iterate based on the previous value and I want to save the results from each iteration in a table/array. I created the empty array beforehand but when I execute the code it return the empty array with the values from the last iteration on the last row.

I am also not sure if the code is actually using the previous value in the way I set it up, but Its not giving errors, so I am assuming its fine(?

Thank you for any help you can provide

results=zeros(500,3);

 for i=1000:100:1500   
     for j=150:50:1608
     
         [y,x]=min (ds(j:j+100,i));
     minpix(i)=j+x;
     
     [y1,x1]=min (ds(minpix(i)-50:minpix(i)+50,i-1));
     minpix(i-1)=minpix(i)+x1;
   
     PixSh= minpix(i-1)-minpix(i);
     
ChangeVel=PixSh/90; 

 results(i,:)=[i ChangeVel PixSh]; 
     end
   
 end

results=zeros([],3);
count = 0 ; 
 for i=1000:100:1500   
     for j=150:50:1608
     
         [y,x]=min (ds(j:j+100,i));
     minpix(i)=j+x;
     
     [y1,x1]=min (ds(minpix(i)-50:minpix(i)+50,i-1));
     minpix(i-1)=minpix(i)+x1;
   
     PixSh= minpix(i-1)-minpix(i);
     
ChangeVel=PixSh/90; 
count = count+1 ; 
 results(count,:)=[i ChangeVel PixSh]; 
     end
   
 end
