how to create return to zero and non return to zero waveform for a random bit sequence

want to generate return to zero and non return zero waveforms for a randomly generated bit sequence

Answer 1

This will return a N-length vector of random [0,1] values:

N = 1000;                   % Length Of Vector
S = randi([0 1], 1, N);     % Create (1xN) Vector Of Random [0 1] Values

thank you but the problem is that it will give vector but i cant display it as a waveform . i want to display a message (containing zeros and ones) as a pulse waveform
