Internal time vectors..

Hello everybody!

after using modulate(Mod,tx) funchtion, we get the Internal Time Vector, right?
so, then how to plot in time domain this signal in Matlab?

for example:

hmod = modem.qammod(M);
M = 16; %16-QAM
tx = randint(500,1,M);

% Modulation
qamSig = modulate(hmod,tx);

qamSig =
1.0000 + 3.0000i
-1.0000 + 3.0000i
-3.0000 - 1.0000i
3.0000 - 1.0000i
-3.0000 - 3.0000i
-1.0000 - 1.0000i
-1.0000 + 1.0000i
3.0000 - 1.0000i
3.0000 + 3.0000i
-3.0000 + 3.0000i
1.0000 + 1.0000i
-1.0000 - 1.0000i

like this stream and how to make a time domain formula of this vector?
the purpose of doing i should find the peak value.
findpeaks(x) can run in time domain
thnks in advance!
