[Octave-bug-tracker] [bug #52647] missing function: erase (introduced Matlab 2016b)

[Rik]

Follow-up Comment #14, bug #52647 (project octave):

@Doug: What is the answer from Matlab for


erase('this is it',['this';'is']) 


If I had to guess, I think the pattern char matrix would be expanded to
['this'; 'is  ']).  The word 'this' will match, but 'is  ' will not, so the
final answer is ' is it'.

Unless of course Matlab is trimming whitespace in patterns, in which case
cellstr rather than mat2cell would be appropriate, but only for patterns.

Also, there was no BIST test for this configuration so no way to know that we
had changed behavior.
