Help me change the Variable R to be the size of $[126]$ instead of $[127]$

$F=$zecos$(1,27)$

$R=$zeros$(1,26)$

$F(1)=0$

$F(2)=1$

$R(1)=0$

$R(2)=0\mathrm{.}5$

for $i=3$:$27$

$F(i)=F(i-1)+F(i-2)$

$R(i)=F\frac{i-1}{F}(i)$

end

$F$

$R$

$x=1$:$27$

plot$(x,F)$

$y\underset{?}{lim}(\left[\begin{array}{cc}0& 5000\end{array}\right])$
