The numexpr package evaluates multiple-operator array expressions many times
faster than NumPy can. It accepts the expression as a string, analyzes it,
rewrites it more efficiently, and compiles it to faster Python code on the fly.
It's the next best thing to writing the expression in C and compiling it with
a specialized just-in-time (JIT) compiler, i.e. it does not require a compiler
at runtime.
Also, numexpr has support for the Intel VML (Vector Math Library) -- integrated
in Intel MKL (Math Kernel Library) --, allowing nice speed-ups when computing
transcendental functions (like trigonometrical, exponentials...) on top of
Intel-compatible platforms. This support also allows to use multiple cores in
your computations.

in multidimensional spaces. Since the module is entirely in Perl (in the
sense that it is not a Perl wrapper around a C library that actually does
the clustering), the code in the module can easily be modified to experiment
with several aspects of automatic clustering. For example, one can change
the criterion used to measure the "distance" between two data points, the
stopping condition for accepting final clusters, the criterion used for
measuring the quality of the clustering achieved, etc.

arithmetic evaluation. Unlike big gui-based software (e.g. Mathematica,
Derive, Matlab, Octave,...) it is intended for use in shell scripting,
together with gnu core utilities.
Its main advantage is that all functions are generalized to operate
on one-dimensional arrays. It can be used for loop indexing (much
like seq), line-by-line arithmetic processing of files, floating
point math for shells that don't support it natively, or interactively,

to make it available to others who also like RPN calculators.

Mersenne Twister (see Math::Random::MT), this algorithm is designed to
take some seed information and produce seemingly random results as output.
However, ISAAC (Indirection, Shift, Accumulate, Add, and Count) has
different goals than these commonly used algorithms. In particular, it's
really fast - on average, it requires only 18.75 machine cycles to generate
a 32-bit value. This makes it suitable for applications where a significant
amount of random data needs to be produced quickly, such solving using the
Monte Carlo method or for games.
