[Octave-bug-tracker] [bug #35481] [var{:}] does not collapse empty elements when some elements are cell

[Ben Abbott]

Follow-up Comment #6, bug #35481 (project octave):

I'd expect each of the assignments below to give identical results. The
results below are from Matlab.


>> a = [1, {}, [], 'a']

a = 

    [1]    'a'

>> a = [{1} {} {[]} {'a'}]

a = 

    [1]    []    'a'

>> a = {1, [], 'a'}

a = 

    [1]    []    'a'


Look to be a Matlab bug.

My guess is that when concatenating inside the square brackets ML is pruning
the empties ([]) before its parser recognizes it is working will a cell array.
When concatenating the cells ML correctly prunes the empty cells ({}).
