No, there is not.
It was new in R2013b, and was not present in R2013a.

This is a helper function used in the example of Designing a Basic Monostatic Radar. The example ships in R2013a so you should be able to find the corresponding helper function used in that release.

I think it is a BUG, so I write the funciton for it.
function helperRadarPulsePlot(pulses,threshold,fgrid,~,num_pulse_plot)
for n=1:num_pulse_plot
subplot(num_pulse_plot,1,n);
plot(fgrid,20*log10(abs(pulses(:,n))),'b','LineWidth',2);hold on;
plot(fgrid,10*log10(threshold)*ones(1,size(pulses,1)),'-.r','LineWidth',1);hold off;
xlabel('Time (s)');
ylabel('Power (dBW)');
title(['Pulse ',num2str(n)]);
end
end
