This is likely the only option:
[h{1},w{1}] = freqz(rand(5,1),1, 2^16, 1000);
[h{2},w{2}] = freqz(rand(5,1),1, 2^16, 1000);
figure
subplot(2,1,1)
hold on
for k = 1:2
plot(w{k},20*log10(abs(h{k})))
end
hold off
grid
subplot(2,1,2)
hold on
for k = 1:2
plot(w{k},unwrap(angle(h{k})))
end
hold off
grid
.
