This is what I have so far:

N1=zeros(201,1);
t=zeros(201,1);
t(1)=0;
N1(1)=10;
N1(2)=20;
delta = 1;
h=1;

for i=2:200
t(i)=i-1;
d=(delta * t(i-1));
N1(i+1) = N1(i) + h*N1(i)*(a-b*N1(i-d));
end
plot(t,N1(:,1)), grid on;

But I'm getting weird plots like this: http://i.imgur.com/4NeseF6.png

Any ideas what I'm doing wrong?
