question on fibonacci sequence.?
max=20
n=zeros(max,1);
n(1)=0;
n(2)=1;
for i=3:max
n(i)=n(i)+n(i-1)+n(i-2)
end
why does we need to write n=zeros(max,1); what does this means?
and please explain how to get this n(i)=n(i)+n(i-1)+n(i-2)?
thanks much.

I assume zeros(max,1) creates an array of max items, the 1 being the number of dimensions. I suppose it could create an array of max 1s, but then why would they call the function zeros.
The n(i)=n(i)+n(i-1)+n(i-2) looks like a programming error. n(i) by either definition of zeros will be a known constant, so it makes no sense. I imagine they intended to write n(i)=n(i-1)+n(i-2).
