[Octave-bug-tracker] [bug #55707] graphics backend takes long when plotting many lines

[anonymous]

Follow-up Comment #10, bug #55707 (project octave):

It seems that MATLAB has used the concept of nullable type
<https://en.wikipedia.org/wiki/Nullable_type>.

>From the documentation
<https://www.mathworks.com/help/matlab/math/creating-and-concatenating-matrices.html>:


"An empty array in MATLAB is an array with at least one dimension length equal
to zero. Empty arrays are useful for representing the concept of "nothing"
programmatically."


All nonabstract MATLAB classes have a method named empty
<https://www.mathworks.com/help/matlab/ref/empty.html>. For example we can
write:


A = int16.empty(5,0);


It means that all non abstract types all nullable. Therefore we can make array
of nulls and iterate over nulls.
--Interesting discussion--
