1. The Fibonacci numbers are computed according to the following relation:
with F0=F1=1.
(1) Write a function, F=fibo(n), to generate Fibonacci numbers in a vector F. Compute the first 10 Fibonacci numbers using the function;
(2) For the first 50 Fibonacci numbers, compute the ratio
It is claimed that this ratio approaches the value of the golden mean . What do your results show?
2. (Optional) Zeller's Congruence is a formula that calculates the day of the week given the date (within a limited range of years). The formula is:
day = 1 + ([2.6m - 0.2] + d + y + [y/4] + [c/4] - 2c) modulo 7
where the square brackets mean take the integer part, modulo 7 means the remainder when divided by 7, and
d = day of the month (e.g. 1 to 31)
m = month number with March=1, ..., December=10, January=11,
February=12. Assign
with F0=F1=1.

咋又来问了，我不是已经帮你做好了吗？
第1题 建立如下的m文件(知道怎么建m文件吗，file->new->m-file，然后把下面的东西敲进去，然后保存file->save，文件名就叫fibo.m)
function f=fibo(n)
if n==0
f=1;
else
if n==1
f=[1 1];
else
temp=fibo(n-1);
f=[temp,temp(end)+temp(end-1)];
end
end
下面是答案
第(1)小题
在命令行里敲
fibo(9)
屏幕就会显示
ans =
1 1 2 3 5 8 13 21 34 55
第(2)小题
在命令行里敲
a=fibo(50);
fibo(49)./a(2:end)
屏幕就会显示
ans =
