arrayfun fails on object arrays.
Searching the bugs on arrayfun I found bug #60680, which is related, but
different. Still I suspect this has been reported before.

class c_tst.


classdef c_tst
  properties
    name;
  end
  methods
    function obj = c_tst(arg)
      obj.name = arg;
    end
  end
end


script tst.m to exercise

c_a = c_tst('number1');
c_a(end + 1) = c_tst('number2');
c_a(end + 1) = c_tst('number3');

{c_a.name}

arrayfun(@(x) x.name, c_a, 'UniformOutput', false);


output of tst.m


ans =
{
  [1,1] = number1
  [1,2] = number2
  [1,3] = number3
}

error: can't perform indexing operations for object type
error: called from
    tst at line 7 column 1
