How can I restart a loop for the same iteration?

Dear all,

Maybe this question sounds odd, but I wonder how I could restart a if-loop for the same iteration (if the user asks for it).

So right now I draw a figure, then I ask the user what to do (Letters coded in a choice/if loop). And one of the options should be to redraw the figure and give again all the options. I think I have to use a while loop from the beginning, but I am afraid I have no idea how to do that...

Thank you for your help,

Katharina

So atm my code looks a bit like

for ...  loop through files
    ... open file, prepare data, draw figure
    choice = input ... 
      if  choice== 'A'  
      ... do stuff with data and exit if loop
      if  choice== 'B'  
      ... do other stuff with data and exit if loop
      if  choice== 'C'  
      ... do stuff 
      ... redraw figure and prompt again these options (???)
     end

save changed data
end

I'd recommend switch case for this purpose and then you can follow Jos' answer to reset the condition variable.

Use a while loop:

k = 0
while k < N
   k = k + 1 ;
   ... do stuff
   if ...
      k = 0 ; % start again
   end
end
