Details:
In Matlab a class can contain a function having the same name as another
class; the purpose of such a function being to convert one object to an object
of a different type. In Octave the converter function is never called, the
class constructor is always called.
It appears that Octave follows Mathwork's published function precedence
(http://www.mathworks.com/help/techdoc/matlab_prog/f7-58170.html#bresuvu-6)
whereas Matlab does not. Octave's behaviour does not allow the creation of
converter functions as such functions can never be called.
Is this a bug in Octave?
Test results:
MATLAB:
>> p2=pcls2
pcls2 constructor
>> pcls(p2)
convert pcls2 to pcls
pcls constructor
>> d=dcls
dcls constructor
pcls constructor
>> pcls(d)
convert dcls to pcls
>> version
ans =
6.5.1.199709 (R13) Service Pack 1
OCTAVE:
octave:1> p2=pcls2
pcls2 constructor
octave:2> pcls(p2)
pcls constructor
octave:3> d=dcls
dcls constructor
pcls constructor
octave:4> pcls(d)
pcls constructor
octave:5> OCTAVE_VERSION
ans = 3.2.3
