The octave-forge package is the result of The GNU Octave Repository project,
which is intended to be a central location for custom scripts, functions and
extensions for GNU Octave. contains the source for all the functions plus
build and install scripts.
This is gnuplot.
Scripts to save data in gnuplot-readable formats, specify gnuplot commands
that will be used to produce graphics, and call gnuplot. See help g_ez
quickly produce the most common plots.

This is level-set.
Routines for calculating the time-evolution of the level-set equation and
extracting geometric information from the level-set function.
Bit::ShiftReg is a perl module that implements rotate left, rotate right,
arithmetic shift left, and logical shift right operations with carry flag for
all C integer types. The results depend on the number of bits with that the
integer types unsigned char, unsigned short, unsigned int, and unsigned long
have on your machine. The module automatically determines the number of bits of
each integer type and adjusts its internal constants accordingly.
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.
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.
This module provides basic functions used in descriptive statistics. It
has an object oriented design and supports two different types of data
storage and calculation objects: sparse and full. With the sparse
method, none of the data is stored and only a few statistical measures
are available. Using the full method, the entire data set is retained
and additional functions are available.

The Set::IntSpan module represents sets of integers as a number of
inclusive ranges, for example '1-10,19-23,45-48'. Because many of its
operations involve linear searches of the list of ranges its overall
performance tends to be proportional to the number of distinct ranges.
This is fine for small sets but suffers compared to other possible set
representations (bit vectors, hash keys) when the number of ranges grows
large. Set::IntSpan::Fast tries to fix that.
Numarray is a reimplementation of the original Python Numeric array
module that provides Python with capbilities similar to Matlab, IDL,
Octave, APL and other array-based languages. This version is still
in its early stages and is not yet the official replacement for
Numeric though we hope it will be before long. It is not fully
backwards compatible with Numeric, particularly with regard to the
C API.
Mpmath is a pure-Python library for multiprecision floating-point
arithmetic. It provides an extensive set of transcendental functions,
unlimited exponent sizes, complex numbers, interval arithmetic,
numerical integration and differentiation, root-finding, linear algebra,
and much more. Almost any calculation can be performed just as well at
10-digit or 1000-digit precision, and in many cases mpmath implements
asymptotically fast algorithms that scale well for extremely high
precision work. If available, mpmath will (optionally) use gmpy to
speed up high precision operations.
ScientificPython is a collection of Python modules that are useful for
scientific computing. In this collection you will find modules that
cover basic geometry (vectors, tensors, transformations, vector and
tensor fields), quaternions, automatic derivatives, (linear)
interpolation, polynomials, elementary statistics, nonlinear
least-squares fits, unit calculations, Fortran-compatible text
formatting, 3D visualization via VRML, and two Tk widgets for simple
line plots and 3D wireframe models.
