Hi Fernando,
Yes, I believe this bug has been mentioned previously. I think it is a
simple oversight and
that you can straightforwardly add the end() method. Note that there
are many other
STL-compliant features that are missing from the blitz::TinyVector
class. These and other
deficiencies have been addressed in the tvmet package, and I am now
working to integrate
tvmet as a replacement for the blitz TinyVector and TinyMatrix classes.
This work will
probably be completed and available in about one month, as my time permits.
Regards, Julian C.
