i have a set of steps which i need to run until a given condition is satisfied. this should run until i get non negative matrix v. this program is a rough draft.This may or maynot give output,i just want to know how to set such conditions.

if true

v=[1 2 -5 7, 4 -8 6 77,-11 -84 25 47,36 -47 -88 99]; zerocoeff=find(v < 0); v(zerocoeff)=0; s=v./(-12); v=v+s

@kitty: Do you know the "{} Code" button already? Your code is short in this question, and it can be read. But using the standard methods in the forum for formatting improves the readability. I had to think twice if the "if true" belongs to the code or is an artifact only.

What is the "condition" you are asking for?

What's wrong with a while loop?

   condition = True;
   while condition
       %do your thing
       condition = something == some_other_thing; %Evaluate to false when you want to break
   end
