[Octave-bug-tracker] [bug #65219] datenum/datestr/datevec: Inconsistent behavior for '' input

[Markus Mützel]

Follow-up Comment #2, bug#65219 (group octave):

Fwiw, in Matlab R2023b:

>> datestr(datenum(''))
Warning: Usage of DATENUM with empty date character vectors or empty strings
is not supported.
Results may change in future versions. 
> In datenum (line 96) 

ans =

  0×11 empty char array

>> datestr(datevec(''))
Warning: Usage of DATEVEC with empty date character vectors or empty strings
is not supported. 
> In datevec (line 103) 

ans =

  0×11 empty char array

>> datestr('')
Warning: Usage of DATENUM with empty date character vectors or empty strings
is not supported.
Results may change in future versions. 
> In datenum (line 96)
In datestr (line 179) 

ans =

  0×11 empty char array

>> datevec('')
Warning: Usage of DATEVEC with empty date character vectors or empty strings
is not supported. 
> In datevec (line 103) 

ans =

  0×6 empty double matrix

>> datenum('')
Warning: Usage of DATENUM with empty date character vectors or empty strings
is not supported.
Results may change in future versions. 
> In datenum (line 96) 

ans =

  0×1 empty double column vector



Empty output seems reasonable for empty input imho.
I didn't check whether they already announced somewhere *how* their behavior
will change for that input.
