Hi All,

Is there any extension for ruby to handle vectors and matrices without
having to loop through arrays? I'm thinking on something similar to Perl
Data Language (PDL):

Thanks,

There''s narray, which you can find on RAA. I don''t know enough about PDL
(or NumPy, another obvious thing to compare) to know if it has
everything PDL does, but it''s got multidim. arrays of int/float/object,
the usual math operators, iteration methods, some statistics, equation
solving.
