How to store values to the matrix and retrieve later as shown below ?

I want to store values on L to J correspondently and make a plot later using J or L(If values can store in L instead J)

p(:,1) = [0;0];
r(:,1) = [0;0];
L(:,1) = [0];
J(:,1) = [0];
syms r1 r2
 
for n=1:0.1:x;
p =[0 (1/3)^n;(1/2)^n 0];
 [V,D]=eig(p);
 
L= [V(2,1)/V(1,1)]
J(1,n)=L
 
end

YOu can further reduce the variables:

m = 10 ; 
L = zeros(m,1) ;
J = zeros(m,1) ; 
x = 1:0.1:m ; 
for i = 1:length(x)
    n = x(i) ;
    p =[0 (1/3)^n;(1/2)^n 0];
    [V,D]=eig(p);
    
    L(i) = [V(2,1)/V(1,1)] ;    
    
end

It has to do from the for loop not x
