Follow-up Comment #1:

Thanks for your bug report. Confirmed here, only affects new-style classdef
based classes.

The code for inputname is very simple, the underlying bug is the value of the
special variable ".argn." in a classdef constructor function.


>> type classtest
classdef classtest
  methods
    function obj = classtest ()
      disp (__varval__ (".argn."));
    endfunction
  endmethods
endclassdef

>> x = y = z = 0;
>> classtest (x, y, z);

{
  [1,1] = y
  [2,1] = z
}
