[Octave-bug-tracker] [bug #61705] Wrong number of columns when removing entry from empty vector

[Vassilis Virvilis]

Follow-up Comment #2, bug #61705 (project octave):

Hi I don't get "invalid operator" for != in 6.2 linux

Looks like ~= and != are the same.

It is even documented at
https://octave.org/doc/v6.4.0/Comparison-Ops.html#Comparison-Ops

I didn't see you replicating the problem in the console output you posted.
Maybe I missed something...

Here is the minimal way to replicate the problem.

octave:6> vector = []
vector = [](0x0)
octave:7> columns(vector)
ans = 0                <---------------- OK

# Now let's remove a non existent entry from a zero size vector

octave:8> vector = vector(vector != 2)
vector = [](0x1)
octave:9> columns(vector)
ans = 1                <---------------- ????
