[Octave-bug-tracker] [bug #49601] strmatch, incompatible result on 'empty' input, (and still around in 2016b)

[Nicholas Jankowski]

Follow-up Comment #1, bug #49601 (project octave):

Matlab:

>> strmatch([],[])
ans =
     1
>> strmatch(ones(0,1),ones(0,1))
ans =
  0×1 empty double column vector
>> strmatch(ones(0,1,0,0),ones(0,1))
ans =
  0×1 empty double column vector
>> strmatch(ones(0,1,0,0),ones(0,1,0,1))
ans =
     1


Octave:


>> strmatch([],[])
error: strmatch: S must be a string
error: called from
    strmatch at line 64 column 5


(same results for the other empty input versions)


Also, matlab does still recommend not using strmatch, and recommends
validatestring (which Octave has) or startsWith (apparently new in 2016b, so
Octave doesn't have a compatible implementation yet)
