How to increase the number of cycles of gaussian modulated sine wave

Hi, The following code -

tc = gauspuls('cutoff',50e3,0.6,[],-40); 
t = -tc : 1e-6 : tc; 
yi = gauspuls(t,50e3,0.6); 
plot(t,yi)

generates a 3 cycle gaussian modulated pusle, how to increase the cycles to 5?

Thanks, Rohan

So does have any idea about this?
