create periodic tasks set

Hi,

I want to create a set of periodic task sets with different period and execution time.I need to generate a code template where if i give a period and execution time then the tasks set would be created..

tasks set would be consists of few nested for loops...i think

for(;;)
  {
for(;;)
{
}
  }
this are execution time
then
sleep()

so, is it the right approach to do so?...I think execution time would be the time taken to execute for loops and period will be execution time of for loops+sleep time.

any suggestions?

Lets say you have execution time and period in vector A and B, respectively. Then you might do something like this:

for i = 1:numel(A) 
   t_in = cputime;
   while((cputime - t_in) <= A(i))
      _Do Your Thing_
   end
   pause(B(i)-A(i));
end

Just want to add that calculating while condition will take some time as well, thus the do your thing will be executed for slightly lesser time than actual execution time.
