   Hello,
   Im trying to make a transducer that can produce low intensity pulsed, how can i used tone_burst_cycles that have 10 cycles which is 2 on and 8 off?

   Hi kamkit,

   There are many ways to do this. You could try using toneBurst with num_cycles set to 2, and 'Envelope' set to 'Rectangular'. Then, append 4 times as many zeros as the length of the tone burst.

   waveform = phased.RectangularWaveform('SampleRate',3.5e6,'PulseWidth',200e-6,...
   'PRF',1e3,'OutputFormat','Pulses','NumPulses',2);
   totaldur = 2*1/waveform.PRF;
   totnumsamp = totaldur*waveform.SampleRate;
   t = unigrid(0,1/waveform.SampleRate,totaldur,'[)');
   q= t.*1000,waveform();
   source.p = q

   i'm trying to create source using rectangular wave, but when I apply kgid.t_array, it broken
