draw 30 cycles of sinusoid oscillating at 10^6 hz

i was trying to plot 30 cycles of a sinusoid oscillating at 10^6, so I tried with following code

>> fs=10^6;

>> T=1/fs;

>> tt=0:0.1:30*T;

>> m=cos(2*pi*fs*tt);

>> plot(tt,m)

but no graph is appear!

%f true
fs=10^6;
T=1/fs;
tt=0:0.1*T:30*T; 
m=cos(2*pi*fs*tt);
plot(tt,m)

Try this
