Details:

Class precedence parameter leads to an error if the class mentioned is not in
the path. Here is the output of the code in example1 (class a is declared as
inferior to class b, which is defined in another folder) :


octave:1> a
error: class not found: b
octave:1> addpath([pwd, '/subfolder'])
octave:2> a
constructor of class a
ans =

<object a>



The fact that a class takes precedence over another one should not be
difficult to fulfill if the other class is not present on the system... Being
unable to use the superior class in this situation is blocking. This is not an
error in matlab.
