how to store the output of for loop

i have this code and i ned to store the value of center_x and center_y in each iteration

for (ii=0:d2:d2*(GW-1)
for(i=1:2:2*GL)
  
plot(i*center_x,center_y,'o') 


end
center_y=center_y+d2;


end

for ii = 0:d2:d2*(GW-1)
   for i = 1:2:2*GL
       plot(i * center_x, center_y, 'o'); 
   end
   center_y = center_y + d2;
end

stored_x = (1:2:2*GL) * center_x;
stored_y = (0:d2:d2*(GW-1)) * d2;

Or start from the creating the positions:

x = (1:2:2*GL) * center_x;
y = (0:d2:d2*(GW-1)) * d2;

for i1 = 1:numel(x)
   for i2 = 1:numel(y)
       plot(x(i1), y(i2), 'o'); 
   end
end

sorted_y return wrong values :(

and the second option dosent work correctly

I do no have the chance to know, what you want as output. All I can see is the code you have posted and your question, that you want to store "center_x and center_y" in each iteration. But center_x does not change its value. Your code dos not run, because the initial values are missing. So all what I can do is showing some methods which store values inside a loop or produce them without a loop. Of course you have to do some tuning to let the code solve your problem. Based on the given information, I cannot do this for you.

"Doesn't work correctly" does not allow to understand, what you observe and what you want instead.
