Use
r = randi([0 1], 1, numElements);
To widen the pulses use movmax().
To control the rise and fall of the pulses, use movmean().

>> r = randi([0 1], 1, numelements );
Error using numelements (line 27)
Not enough input arguments.
Do we need to input elements?

Of course. What did you use for the number of elements you want in your random array? How about 10 or 900 or 777777? I have no idea what you need.
