Call function and save results

Hi. I have a while loop that iterates through all images in a datastore, and calls a function passing each image. The function returns three values, and I want to save them so I can view all values that are returned. There are 50 images in the datastore.

I am trying to be able to view all the values that are returned and saved in column a, but this does not work. What am I doing wrong?

results = zeros(50,3)
iterations = 0;

while hasdata(ds)
img = read(ds);
[a, b, c] = myFunction(img);      
  
   results(iterations+1,1) = a;
   results(iterations+1,2) = b;
   results(iterations+1,3) = c;
   
   iterations = iterations + 1; 
end

for x = results(a)
   disp(x)
end

Maybe just display the results:

disp(results);

Or loop differently:

for k = 1:size(results,1)
   disp(results(k,:))
end
