MATLAB: Fibonacci Sequence Recursion, Help!

fibonaccirecursion

So, I have to recursively generate the entire fibonacci sequence, and while I can get individual terms recursively, I'm unable to generate the sequence. I already made an iterative solution to the problem, but I'm curious about a recursive one. Also, fib(0) should give me 0(so fib(5) would give me 0,1,1,2,3,5). Here's what I tried:
%
function[y]=fib_recur(n)
y = zeros(1,n);
fib(n);
y=[0 y]
function y = fib(n)
if n<3
y(1:n) = 1;
else
y(n) = fib(n-2) + fib(n-1);
end
y = y(n);
end
end

Best Answer

Several issues:
(1) the result of fib(n) never returned. (2) Your fib() only returns one value, not a series
You can change your third line,
fib(n)
to
for m = 1:n
y(m) = fib(m);
end
so you can build an array.
