Details:

Using the following class:


classdef myclass < handle

  methods
    function obj = myclass
    endfunction

    function methodA (obj, varargin)
      varargin
    endfunction

  endmethods

endclassdef


call the methodA() method on a myclass object:


>> obj = myclass ();
>> str = "Octave";
>> methodA (obj, str);
varargin =
{
  [1,1] = Octave
}
>> obj.methodA (str);
varargin =
{
  [1,1] = Octave
}
>> methodA (obj, str(1:end));
varargin =
{
  [1,1] = Octave
}
>> obj.methodA (str(1:end));
varargin = {}(0x0)
error: invalid dimension inquiry of a non-existent value


The error seems to be linked to the use of 'end' in the method call, ie it
works with str, str(1:5) or with 'val' having been previously defined as
str(1:end).
