The octave-forge package is the result of The GNU Octave Repositry 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 interval. The interval package for real-valued interval arithmetic allows to evaluate functions over subsets of their domain. All results are verified, because interval computations automatically keep track of any errors. These concepts can be used to handle uncertainties, estimate arithmetic errors and produce reliable results. Also it can be applied to computer-assisted proofs, constraint programming, and verified computing. The implementation is based on interval boundaries represented by binary64 numbers and is conforming to IEEE Std 1788-2015, IEEE standard for interval arithmetic.

The Math::FFT module provides an interface to various Fast Fourier Transform (FFT) routines of the C routine of fft4g.c; The one-dimensional data sets, of size 2^n, are assumed to be sampled at a constant rate. The FFT methods available are - cdft: Complex Discrete Fourier Transform - rdft: Real Discrete Fourier Transform - ddct: Discrete Cosine Transform - ddst: Discrete Sine Transform - dfct: Cosine Transform of RDFT (Real Symmetric DFT) - dfst: Sine Transform of RDFT (Real Symmetric DFT) as well as their inverses. The C code for the FFT routines of fft4g.c is copyrighted 1996-99 by Takuya OOURA. The file arrays.c included here to handle passing arrays to and from C comes from the PGPLOT module of Karl Glazebrook <kgb@aaoepp.aao.gov.au>. The perl interface of the Math::FTT module is Copyright 2000 by Randy Kobes <randy@theoryx5.uwinnipeg.ca>, and may be distributed under the same terms as Perl itself.

The Numeric Extensions to Python give Python the number crunching power of numeric languages like Matlab and IDL while maintaining all of the advantages of the general-purpose programming language Python. These extensions add two new object types to Python, and then include a number of extensions that take advantage of these two new objects. * Multidimensional Array Objects + Efficient arrays of homogeneous machine types + Arbitrary number of dimensions + Sophisticated structural operations * Universal Function Objects + Supports mathematical functions on all python objects + Very efficient for Array Objects * Simple interfaces to existing numerical libraries: + Linear Algebra (LAPACK) + Fourier Transforms (FFTPACK) + Random Numbers (RANLIB) _____________ Note: Development for Numeric has ceased, and users should transisition to NumPy as quickly as possible.

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.

This library of routines is part of a reference implementation for the Dense and Banded BLAS routines, along with their Extended and Mixed Precision versions, as documented in Chapters 2 and 4 of the new BLAS Standard. EXTENDED PRECISION is only used internally; the input and output arguments remain the same as in the existing BLAS. At present, we only allow Single, Double, or Extra internal precision. Extra precision is implemented as double-double precision (128-bit total, 106-bit significand). The routines for the double-double precision basic arithmetic operations +, -, *, / were developed by David Bailey. We have designed all our routines assuming that single precision arithmetic is actually done in IEEE single precision (32 bits) and that double precision arithmetic is actually done in IEEE double precision (64 bits). The routines also pass our tests on an Intel machine with 80-bit floating point registers. MIXED PRECISION permits some input/output arguments to be of different types (mixing real and complex) or precisions (mixing single and double).

`gnuls' is a port of the GNU colorized `ls' program--the one most Linux users are familiar with. The port installs four programs in `/usr/local/bin': `gnuls', `dir', `vdir' and `dircolors'. It also installs man pages for all four programs. See the individual man pages for details on each program. NOTES: 1. This port modifies the GNU `coreutils' make procedure so that it installs only programs and man pages listed above. In particular, it does not install the various GNU info files associated with the programs. 2. This port installs GNU's `ls' as `gnuls' so it won't conflict with the normal BSD `ls' program or the BSD `colorls' program (the latter available from the ports collection). 3. This colorized `ls' program is not the same as the `colorls' program available from the ports collection.

kcd allows user to change directory by using various methods: - By using cursor keys to navigate through the directory tree screen - By searching in directory tree screen - By typing part of the directory name directly at the command line. Other features include: - Can be configured to filter out to some subdirectories, useful for cdrom and msdos partition mounting points - Can be configured to scan directory tree starting from some specified directory inwards, for example, home directory. - If the number directories that matches to the name given in the command line exceeds a specified number, kcd displays the whole list. - Faster directory rescan if old data file exists. Only directories with newer modified/changed time are scanned. - Sorted directory tree listing.

GNU VCDImager is a full-featured mastering suite for authoring, disassembling and analyzing Video CD's and Super Video CD's. The core functionality consists of directly making Video CD BIN/CUE-style CD images from mpeg files. Features - Free software available under the GNU Public License - Support for Video CD 1.1 and 2.0 disc formats - Support for the Super Video CD 1.0 disc format - Full PBC (playback control) support - Support for segment play items - Automatic padding of MPEG streams on the fly - Support for 99-minute (out-of-specification) CD-R media - Extraction of Video CD's into files (incl. the PBC information) - Use of XML for the description of Video CD's http://www.vcdimager.org/

The EXTended RECordings MENU plugin provides additional functions to VDR's recordings menu: * renaming recordings and directories * moving recordings and directories, also between different filesystems * adjustable display of recording's length, date and size * directories are always shown on top of the list * reworked layout using icons for showing the status of list entries (directory, new recording, moving recording/directory, cutting recording, dvd archiv entry) * extended recordings info menu, shows name, path, channel, size, lifetime and priority of the recording * free disk space is shown for the filesystem of the current directory * sorting by name or date, adjustable for each directory; type of sorting will be stored * ascending/descending sorting * extends VDR's '-r'-option commands with 'move' and 'rename' * functionality of the DVDArchive-patch (see below) * protecting recordings in co-work with the PIN-plugin * a cutter queue
