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.
