It seems it has some errors in some versions of MATLAB.
like errors in link quality model(line 688), NetworkElements/user(line 194) or schedular.roundrobinschedular(line 107).
and when I use its mimo application(use more than one antenna for transmitting) there are some errors(I have changed the channel model type in setting/user/parameter from AWGN to extPedB)in it like error in linkqualitymodel(line 759) .
for now, the simulator only supports SISO transmission (we have prepared most parts for MIMO, but still need to implement feedback etc.). Therefore, I’m not sure if it is a problem with the MATLAB version. Did you get the same error when using the default parameters for the scenarios? Which version of Matlab are you on?
