Try something like this —
h(1) = rand; % Initial Condition
h(2) = rand; % Initial Condition
N = 50;
for n = 3:N
h(n)=-0.36*h(n-2)+1.2*h(n-1);
end
nv = 1:N;
figure
plot(nv, h, '.-')
grid
xlabel('n')
ylabel('h')
Experiment to get the result you want.

I don't know your code, but as you can see above, plotting is possible.
nv and h are both vectors of size 1 x (10/T+1) (1 x 26 for T = 0.4).
101 smells like T = 0.1 while 26 smells like T = 0.4. I think you somehow mixed the two stepsizes for T in the h and nv arrays.
