k=[3 8 10 12]

i wanted to execute above mentioned indexes in for loop something like this

for i=[3 8 10 12]
    if i==3
        do stuff
    end
    if i==10 
        do stuff
        .
        .
        .
    if i==12
         do stuff
    end
 end

i don't know vector k elements before hand.

@Michael, yes it's the same for a hardcoded k, but if k is an input to the function, then it's not:

k = randi(3, 1, 5);
for action = k
   switch action
      case 1
          disp('do action 1');
      case 2
          disp('do action 2');
      case 3
          disp('do action 3');
   end
end
