Hi, I need to exit from a loop,should i use break ?

here is an example :

for j=1:10
  if (condition 1)
    a=5;  % example
    % continue step
  elseif (condition 2)
    a=2;
    % continue 
  elseif (condition 3)
      a=0; 
      % !!! reject step
      break; % !!
  end

Simply try it:

a = 0;
for j = 1:10
  fprintf('j=%d  a=%d\n', j, a);
  if j < 3
    a = 5;
  elseif j < 6
    a = 2;
  elseif j == 8
    a = 0;
    fprintf('Breaking the loop...\n');
    break;
  end
  fprintf('  >> next iteration\n');
end
fprintf('Loop finished. a=%d\n', a);
