If y(j) is less than some number (say 3) then I want to use higher value of k (say 4) but in the range of 5th iteration before and after y becomes 3. For example in 40th iteration y becomes 3. I want to use k=7 from 35th to 45th iteration. Pls help.

N=100;
dt=0.05;
k=2;
t=zeros(N,1);
y=zeros(N,1);
y(1)=2;t(1)=0;
for j=1:N-1
t(j+1)=t(j)+dt;
y(j+1)=y(j)+dt*(2+k);
end
plot(t,y)

Your question is quite confusing, because the criteria seems to be depend on several things that are not really clear.
Regardless, what stops you from using an if statement to choose k, based on the value of y(j), or iteration, etc?
