This perl library aims to provide as many tools to make it as simple as possible
to calculate distances between geographic points, and anything that can be
derived from that. Currently there is support for finding the closest locations
within a specified distance, to find the closest number of points to a specified
point, and to do basic point-to-point distance calculations.
This is Graph, the Perl module for graph operations as the code was for
the 1st edition of "Mastering Algorithms with Perl", by Jon Orwant,
Jarkko Hietaniemi, and John Macdonald, published in August 1999 by the
O'Reilly and Associates.

Package KFAS provides funchtions for Kalman filtering, state,
disturbance and simulation smoothing, forecasting and simulation
of state space models. All functions can use exact diffuse
initialisation when distributions of some or all elements of initial
state vector are unknown. Filtering, state smoothing and simulation
functions use sequential processing algorithm, which is faster than
standard approach, and it also allows singularity of prediction
error variance matrix. KFAS also contains function for computing
the likelihood of exponential family state space models and function
for state smoothing of exponential family state space models.
RPy is a very simple, yet robust, Python interface to the R Programming
Language. It can manage all kinds of R objects and can execute arbitrary
R functions (including the graphic functions). All the errors from the
R language are converted to Python exceptions. Any module that later were
installed on the R system, can easily be used from within Python, without
introducing any changes.
Number::Compare compiles a simple comparison to an anonymous subroutine,
which you can call with a value to be tested again.
Now this would be very pointless, if Number::Compare didn't understand
magnitudes.
The target value may use magnitudes of kilobytes (k, ki), megabytes (m,
mi), or gigabytes (g, gi). Those suffixed with an i use the appropriate
2**n version in accordance with the IEC standard:

Number::Fraction is a Perl module which allows you to work with fractions
in your Perl programs.
Number::Misc provides some miscellaneous handy utilities for handling
numbers. These utilities handle processing numbers as strings,
determining basic properties of numbers, or selecting a random number
from a range.
Set::IntSpan manages sets of integers. It is optimized for sets that
have long runs of consecutive integers. These arise, for example, in
.newsrc files, which maintain lists of articles:
alt.foo: 1-21,28,31
alt.bar: 1-14192,14194,14196-14221
Sets are stored internally in a run-length coded form. This provides
for both compact storage and efficient computation. In particular,
set operations can be performed directly on the encoded
representation.
A Set::Window object represents a window on the integer line; that is, a
finite set of consecutive integers.
Methods are provided for creating and modifying windows, for obtaining
information about windows, and for performing some simple set operations
on windows.
