How to use timer command?

How can I use timer to compare each row of the file for 0.2 sec and compare the azimuth column which is present in the comparing file. Doubt is: My covarage area is from 310 to 200 degree, for every 10 degree I need to compare whether azimuth is matching or not.

My Code:

load target.dat %contains 300 rows
for i=1:300
    t=timer('TimerFcn',@myfun,'Period',0.2 ) ;
    start(t);
    delete(t);
end
function myfun()
  for r=1:300
      if target(r,2)>=310&&target(r,2)<=60
          %eg:if the value in azimuth column is
          %lies between 310 to 320 send that row
          %of file which i am comparing (do this
          %til reaching 60 degree)
          %send 1 packet
      elseif target(r,2)>60&&target(r,2)==90
          %send 2 packet
      else target(r,2)>90&&target(r,2) <=200
          %send 1 packet
      end
  end
end

Please help me out in solving this. Thanks in advance.

I reformatted your code for you; please check for correctness.

Note that

else target(r,2)=90&&target(r,2) <=200

means the same as

    else
        temp = 90 && (target(r,2) <=200);
        target(r,2) = temp;
        disp(target)

I see you changed your code. Note, however, that

else target(r,2)>90&&target(r,2) <=200

is equivalent to

 else
     temp = (target(r,2)>90) && (target(r,2) <=200);
     disp(temp)

If you want a test then you need elseif -- and remember to always have an else in case none of the situations matched.
