h(1) = 0;
T(1) = 273.15;
p(1) = 101.2;
for t = 1:328084
if h(t)<[11000]
T(t+1) = 15.04 - 0.00649.*h(t);
p(t+1) = 101.29 .*((T(t) + 273.15) /288.08).^5.256;
elseif [11000]> h(t) && h(t)<=[25000]
T(t) = -56.46;
p(t+1) = 22.65.*e^(1.73-0.000157.*h(t));
elseif h(t)>[25000]
T(t) = -131.21+0.00299.*h(t);
p(t+1) = 2.488 .* ((T(t) + 273.15)/216.6).^-11.388;
end
rho_h(t) = p(t) ./(0.2869 * (T(t) + 273.15))
end

h(1) = 0;
That is the only place you assign to h
if h(t)<[11000]
but you need h to be 328084 elements by the end of the loop.
