Paul,
Thanks for your response. I do not have a great deal to complaint at the
moment. As many of Python related stuff, I was fully expecting things are on
the process status as usual. I was just merely trying to gather info if
available.
If you have anything simple code that takes numeric as arg and return
numeric back for Cxx, I would appreciate it. As I understand it, Cxx is
currently for one dimension only? Is any improvement in works?
Anyway CXX is a wonderful change, however, from the C interface, which I
could never figuire out. I don't know C++, bu t it took me basically 2-3
hours to go through the example and I am writing a fairly complicated data
interface with it already. I am so happy about finally being able to wrap
stuff in C.
One small Q if you don't mind. How does one append list to a list (or
Tuple)? So far this is what I have come up with.
a.append(aux) apparently send out address of not the values of aux. This is
quite diff from way Python does it normally.
This will do what I want it to, but a little bit ugly.
List a, Nada;
List ans, aux;
aux.append(Int(3));
aux.append(Float(6.0));
a.append(Float(0.0));
a.append(aux);
a.append(Tuple(aux));
aux.append(Float(99.0));
aux = Nada;
aux.append(Float(111.1));
a.append(Tuple(aux));
Thank you much for everything.
