[Octave-bug-tracker] [bug #53005] Variable editor: slow performance with large arrays

[Dan Sebald]

Follow-up Comment #3, bug #53005 (project octave):

That is rather slow, even the initial creation and display of the 1000 x 1000
table.  That's big, but not huge.  I can imagine a spreadsheet of that size.

As far as update, my thought was that given a general way of processing
commands in the background, the variable editor would do something like

[V.E. modifies the value and initiates an update]
[The innards issue an "x(i,j) = newvalue"]
[If there is a success of the above command, then update the cell contents by
calling "x(i,j)"]

I would hope that the Qt table can quickly handle the update of that value
rather than have to fill in the whole table again.
