How to plot matrix inside for loop ?

clc
close all   
A=[0 3/10;3/5 0];
u=[0.3 ;0.8]; 
p=[0;0];
 
for n=1:50
    
 p=A*p + u;


plot (n,p(1),'-');hold on
plot (n,p(2),'-');hold on

end

So there are values coming to the p(1) and p(2) in p , so it starts from 1 to 50 and i want to put those p(1) and p(2) in to a plot and it has to be drawn using a line . so my code doesn't draw lines but it draws dots .

Like this?

A = [0 3/10;3/5 0];
u = [0.3 ;0.8]; 
p = nan(2,51);

% Inisital condition
p(:,1) = [0;0];

for n=1:50
 p(:,n+1) = A*p(:,n) + u;
end

% Plot the result
figure
plot(0:50,p(1,:))
hold on
plot(0:50,p(2,:))

Answer 2

[Andrei Bobrov]

A = [0 3/10;3/5 0];
u = [0.3 ;0.8]; 
p = [0;0];
P = zeros(2,50);
for n = 1:50
    p = A*p + u;
    P(:,n) = p;
end

plot (P.');
