I will note that R2019b is a very new version of Octave and we often choose to follow Matlab slowly.  They can introduce functions in one version and subsequently tweak their arguments and implementation before finally settling in on the behavior of the function.  If we follow Matlab too closely then we often end up doing unnecessary work trying to chase compatibility as they change their own API.

I have just "discovered" two new Matlab plotting commands. They were introduced to Matlab in R2019b.

They work as following:

tiledlayout ('flow')
nexttile
plot(1:10)
nexttile
plot(2:20)

This produces one plot window with two subplots. Similar (identical?) to what you get with the following code both in Matab as in Octave:

subplot(2,1,1)
plot (1:10)
subplot(2,1,2)
plot(2:20)

Maybe we should at least add them to the missing command list in Octave, now. (And maybe implement them at some time as well?)
