How can I put the value of z in a matrix and later call it as z(1,i) and z(2,i) in the while loop?

close all;
dt = 0.1;%time step
u1=1;
u2=1;
c = u2-u1;
u = sign(u2-u1);
z = u*c;
k=0.12;
m=2.21;%initial parameters
v=1;
a=1.4;
tend=1000;
t=0;
i=1
while t < tend-2*dt
vh=v(i)-dt*k*z(i)/ (2*m);
z(i+1) = z(i)+ dt*vh;
%a(i+1)= -k*z(i)/2;
v(i+1)= vh-dt*k*z(i+1)/ (2*m);% + dt*a(i+1)/2;
i = i+1;
t = t + dt
end
plot(z);

If you want a matrix of 2 column with changing row values then you can do like this:-
while i<t
Z(2,i)= z(1,i)+dt*vh;
i=i+1
end
