[Octave-bug-tracker] [bug #35400] Performance of in-place operations

[Hartmut]

Follow-up Comment #2, bug #35400 (project octave):

This issue is still (partly) present in Octave 4.2.0.

I now get the following result from the test script:

>> bm_accum

Elapsed time is 1.48891 seconds.
Elapsed time is 0.643239 seconds.
Elapsed time is 0.648474 seconds.


So we somehow improved the performance of the second command to match the
third one. But the first one is still slower by a factor of two.

Would it be feasible at all, to perform the first (and most general syntax)
command "x = x + 1" as an in place accumulation at all? If "no", then let's
close this issue. If "yes", then let's keep it open.
