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!

The reason no graph appears is because your variable tt contains only one element (0).
The value of 30*T is 3*10^-5, so you need to use a smaller step than 30*T to declare tt as an array of values.
