Follow-up Comment #4, bug #68172 (group octave):

noting that matlab also errors when called on a cell array while octave does
this:


octave:7>  foo = {1,2;a,b};

>> any(foo)
ans = [](0x0)

>> all(foo)
ans = [](0x0)


not familiar with the classdef code, but would it be better to handle this as
better input validation in any and all rather than within classdef overloads?
