function de=equivalent(d)Â Â Â Â Â Â %d
is input for function in degrees
   if(d<0)
       while(d<0)
          Â
d=360+d;Â Â Â Â Â Â Â %while d is
lessthan zero add 360 for d
       end
   end
   if(d>360)
       while(d>360)
          Â
d=d-360;Â Â Â Â Â Â Â %while d is
greaterthan zero substract 360 from d
       end
   end
   de=d;     Â
%return the remaining d
end
Output:- in Command window
