A) it's the single biggest ruby project after rails.  think about that!

B) take 50% of the list where people say 'ruby is too slow at XXXX' or  
why can't i do 'XXX' - the gsl is by far the largest container of  
algorithms on rubyforge, but orders of magnitude, it's not just  
science: scan this list

   http://rb-gsl.rubyforge.org/ref.html

and you'll see things like 'complex numbers', 'vectors', 'matrices'  
'permutations', 'FFT', 'random number generation', 'statistics', and  
'NArray compatibilities'

scan the list of ruby quizes and you'll see where i'm headed ;-)

sure.  the fact that these two libs work together is immensely powerful.

check this out

and here is the code

http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/155483

using narray in combination of mmap.
