I'm trying to simulate an environment with multiple target with phased.freespace channel. The signal I used is Linear FMCW signal. But i found this error:
Error using phased.FreeSpace/validateNumberOfPositionPairs (line 231)
Expected input Pos2 to be of size [3 1] when it is actually size [3 28].
Error in phased.internal.AbstractFreeSpace/validateInputsImpl (line 333)
validateNumberOfPositionPairs(obj,x,startLocSize,endLocSize);
Error in FMCWExample_multi_target (line 191)
txsig = channel(txsig,radar_pos,tgt_pos,radar_vel,tgt_vel);
Can anyone give me a hand?

What are dimensions of your inputs to the object? You may need to match the number of input signal to number or targets.
