The signal should be
initial delay in few nano sec
three pulse around 200 ns period
after three cycles the signal should have zero till all time
MATLAB: Only three pulse generation
pulse train

The answer is No! .I am not aware of any function which can do that for you. Try to adapt my function for your needs or write your own.
