How do i edit the program in the fllwn below, that while WB runs when it reaches between 27500 and 28500,the step changes from 50 to 100 between that range and then continues with 50 after??

for WB=25000:50:29000; Para(9)= WB; ff= ode5(@this_eq_of_motion,t,Y0,Para); % the ode4 Resp=ff(80*1/delta_t:end,:); save(strcat('res_to_WOB_', num2str(WB),'.mat'),'Resp','Para'); Y0 = ff(end,:); Y0(4)=0; clear ff Resp end

What is a "fllwn"???

I did this:

for WB=25000:50:29000;
  WB
end

and I saw no evidence that it changes the step size.
