How do I save my values of x each time the loop goes round?

This is my Matlab code. How do i change it so that each value of x is stored when the loop goes round? I'm trying to plot it and compare.

%IC
clear
x = 1;
time = 0;
dt = 0.1;
%for loop calculating x after 10 iterations
for n = 1:10;
    k1 = 4*x+2*time-3;
    k2 = 4*(x+(tchange*k1))+2*(time+dt)-3;
    xnew = x+((dt/2)*(k1+k2))
    x = xnew;
    time = time + dt;
end

Help would be appreciated! :)

%IC
clear
x = 1;
time = 0;
dt = 0.1;
%for loop calculating x after 10 iterations
xx = zeros(10,1) ;
for n = 1:10;
    k1 = 4*x+2*time-3;
    k2 = 4*(x+(tchange*k1))+2*(time+dt)-3;
    xnew = x+((dt/2)*(k1+k2))
    x = xnew;
    xx(n) = x ; 
    time = time + dt;
end
plot(xx)

thank you! how do I plot this against time? (from 0 to 1 as there are 10 timesteps of 0.1)
