[Octave-bug-tracker] [bug #33537] lower function returns incorect result on numerical values

[Michael Godfrey]

Follow-up Comment #3, bug #33537 (project octave):

I do not think that anyone would say that Matlab
is "right" in this case:

Matlab says, for more examples:

lower([ 90 100])

ans =

    90   100
>>
but also:
>> lower([ 90 100 'ABC'])

ans =

zdabc

>> 
This matches Octave!

Other experiments may be a good idea, but this is not
worth much time, I think.  A simple solution for the
case above would be isnumeric() applied to the argument
and then do as Matlab seems to do.

Regardless of Matlab, I do not think that Octave doing:
octave:35> lower(64)
ans = @
octave:36> lower(65)
ans = a
octave:37> 
is very helpful.  Probably, Matlab choice would be better.
