The question is not clear yet. What does "rejecting a step" mean?

Yes, and you do this already with the break command. So the code does already what you are asking for,

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);
