[Octave-bug-tracker] [bug #52988] Variable editor: allow scalars to be shown directly

[John W. Eaton]

Follow-up Comment #9, bug #52988 (project octave):

I'm not seeing segfaults, but I do see the performance issue with
automatically adjusting the column widths for large arrays.

A 5000x5000 array requires almost 200MB for the numbers alone and more than
that to cache the (short, limited to about 8 characters but sometimes more)
string representations of the numbers and the associated QVector object that
is used to store the info in the Qt model object.  With autofit enabled, I
think Qt must generate the full list in the model.  With it disabled, then
only what is displayed needs to be generated.  I suppose we could disable it
by default for arrays larger than some limit.

Just out of curiosity, how does Matlab perform for a similar sized array?
