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

change to this line
tt=0:T/100:30*T
