[Octave-bug-tracker] [bug #51962] "A++" assigns to 'ans' while "A += 1" and "A = A + 1" do not

[Rik]

Update of bug #51962 (project octave):

                 Summary: ++ and -- not same as +1 and -1 => "A++" assigns to
'ans' while "A += 1" and "A = A + 1" do not

Follow-up Comment #3:

I re-titled the bug report, but yes, this is ordinary and expected Octave
behavior.  Whenever you execute an operation, for which no variable is
assigned, then the default variable 'ans' gets the output.

The easy workaround, as mentioned, is to use assignment so that 'ans' is not
created.  Alternatively, you could look at using a different algorithm that
doesn't use so much memory.  If your matrices are large, but mostly 0
elements, then use sparse arrays.  And as a last resort, just run on a machine
with more memory.
