How Fast is Ruby cpr. Perl, Python, Tcl , C++, Java - Arithmetic

[vsapre80]

Hi,

How fast is Ruby as compared to Perl/Python/Tcl/Java/VB/C++/C

in its Arithmetic performance ?

Any answers, comparative studies etc etc

Certainly Ruby will be much slower than C/C++ for arithmetic. Probably
quite a bit slower than Java now too.

However, it's quite easy to extend Ruby with C and implement certain time
consuming arithmetic intensive functions in C and call them from Ruby
(I've done this and generally speaking it speeds things up quite nicely).

How can you carry over the seamless handling of large integers into
C though?

pure ruby math is quite slow.
Luckily, there are quite a bit of modules to allow you to do
fast math: look for Narray, ruby/GSL, ruby/Rmath etc.. or simply
navigate the "math" directory in raa:

Which one, however, is most appropriate among Ruby tools if I want to
use instead of MATLAB, i.e, for linear algebra mathematics? For example,
in Python, there is *NumPy* that is one of the most popular tools for
mathematical processing in Python.

*Numpy represents Numerical Python.
