Starting with this year's Matlab Version R2019a the new function "readmatrix"
was introduced by Mathworks. They now marked the good old "csvread" and
"dlmread" with the following comments:

Not recommended starting in R2019a

csvread is not recommended. Use readmatrix instead. There are no plans to
remove csvread.

(Same for dlmread.)

I think we should

* add readmatrix to the list of "unimplemented" functions in Octave, soon.

* Consider creating an Octave version of readmatrix in the future. Since
importing csv data files is in my understanding a core functionality of
Octave. (Before processing your data, you need to first import it.) And Matlab
users will probably change over to this readmatrix function during the years
to come.

But creating a "readmatrix" function seems to not only be a wrapper around any
existing Octave function. They support quite many (useful?) options in ths new
function readmatrix.
