Why does this example from MathWorks work on Windows but not on Mac?

2 views (last 30 days)
I'm trying to run this example straight from the MathWorks LeanerFMWaveform page.
fs = 500e3;
sLFM = phased.LinearFMWaveform('SampleRate',fs,...
'SweepBandwidth',200e3,...
'PulseWidth',1e-3,'PRF',1e3);
lfmwav = step(sLFM);
nsamp = size(lfmwav,1);
t = [0:(nsamp-1)]/fs;
plot(t*1000,real(lfmwav))
When I run it on MATLAB on Windows, it works as expected and plots the signal. When I run it on MATLAB on Mac, I get this error:
Error using plot
Too many input arguments.
I'm running version R2021a on both operating systems. Why is this not working on Mac?

It's not win v. mac but that you've shadowed plot on the failing machine.
