How to create a vector of the ratio of two successive Fibonacci numbers

n=input('Your Fibonacci sequence number that you want to find between 20 and 40 is ')

f=zeros(n,1);

f(1)=1;

f(2)=1;

for x=3:n;

    f(x)=f(x-1)+f(x-2);

end

sprintf('Your fibo sequence is')

f

This part of the code was to create a vector of a fibonacci series to a user inputted number n, but what I can't figure out is the title. Creating and plotting a vector length (n-1) that will plot the ratio of two successive fibonacci numbers. i.e. plotting the Golden Ratio

Hi,

try this

figure;
plot(f(2:end)./f(1:end-1))
