Performance of RevMedia on matrix diagonalization

[Piero Ugliengo]

Hi Bernard, you are certianly right about RB. Indeed I am following their
developmentduring the years. I am pretty sure that the same code will be
probably faster in RB than in VB6
but I have yet to decide to buy their compiler.
As you said, what is attractive in RevMedia is its free character and the
fact that one can
write a trully portable app running within any browser. It is also rather
easy to
adopt as a language for teaching programming concepts to people in the
scientific field without
the effort needed with Java or C++. Python is certainly a beautiful language
extremely reach
in features and ad hoc libraries and can be adopted as a general purpose
language also
in a scientific context (Numpy will solve almost all numerical aspects). On
the other hand
I still have to find an easy way to deploy to a final user a complex Python
application which would
be straightforward to install on his/her computer.
Cheers
Piero
