does anybody know of any good, high-speed numerical ruby libraries, kind of
like numpy for python? any help is appreciated.

ruby and 'high speed' are sort of antithetical terms.

Apart from the possibilities others have mentioned, there is also
JRuby, which makes it easy to include Java code in a Ruby program.
I've used JRuby writing my own Java code for the numerical processing
which needs to be fast. I haven't tried using "standard" Java
libraries, but I assume that if one can include one's own Java
"libraries" in a Ruby program, it shouldn't be too hard to do that
with standard Java libraries.

No they're not, and what serialhex was asking about is completely reasonable. Numpy is a
C-based Python library that provides high-speed math operations of all sorts. Since Python and
Ruby 1.9 are quite comparable in terms of performance, it's not at all unreasonable
to ask if a counterpart to numpy exists for Ruby. Your dismissal is unwarranted.
http://narray.rubyforge.org/ is an old library that handles matrix and vector operations.
It doesn't offer all of numpy's options. Unfortunately, there are few alternatives for Ruby.

SWEET!! thank you both Matz & Michael, NArray looks like it might work for
what i'm looking at.

I know a little python, myself.

What? Where?

narray is great. and if you need more capabilities, there are several
GSL bindings (I still use rb-gsl.rubyforge.org).
I've been using ruby for "fast" numerics and regular calculations for
a number of years, and been quite happy with them.

Here's the shootout results for:
1.9 vs. Python 2.x:
http://shootout.alioth.debian.org/u32/benchmark.php?test=all&lang=yarv&lang2=python
1.9 vs. Python 3:
http://shootout.alioth.debian.org/u32/benchmark.php?test=all&lang=yarv&lang2=python3
PyPy does a bit better, but the shootout doesn't support Rubinius. A 1-3x difference
is quite comparable when both languages are currently up to 2 orders of magnitude
slower than others. Plus Ruby even wins some benchmarks by smaller margins.
