This package provides expandable operations for tuples of numbers: len, sum, min, max, mean, med, quantile, standard deviation, get item, position of item sort, add or set items, filter, operations, composition, split, formatting and display.

This package provides tools to generate a PK file from an Adobe Type 1 font. PK fonts are (or used to be) valuable in enabling previewers to view documents generated that use Type 1 fonts.

The mcite package allows the user to collapse multiple citations into one, as is customary in physics journals. The package requires a customised BibTeX style for its work; the documentation explains how to do that customisation.

The Droid typeface family was designed by Steve Matteson. The Droid family consists of Droid Serif, Droid Sans and Droid Sans Mono fonts. The bundle includes the fonts in both TrueType and Adobe Type 1 formats.

This LaTeX package generates a completed standard form 298 (Rev.: 8-98) as prescribed by ANSI Std.: Z39.18 for report documentation as part of a document delivered, for instance, on a U.S. government contract.

This is the original, and somewhat dated, TeX chess font package. Potential users should consider skak (for alternative fonts, and notation support), texmate (for alternative notation support), or chessfss (for flexible font choices).

Astrosym is a font containing astronomical symbols, including those used for the planets, four planetoids, the phases of the moon, the signs of the zodiac, and some additional symbols. The font is distributed as Metafont source.

MFLua is an extension of Metafont which embeds a Lua interpreter. It doesn’t introduce any new primitives, so a Metafont file can be used with MFLua without any modification to produce exactly the same result.

This small package aims to provide two simple commands and many options to easily write linear operators as they appear in many-body physics, quantum theory, and linear algebra, in any of the ways commonly in use.

The file processes to produce (real) rulers; the author suggests printing them on transparent plastic and trimming for use as a real ruler. The rule widths are 0.05mm, which can be challenging for (old) laser printers.

The Plain TeX program (typed in the shape of the towers of Hanoi) serves both as a game and as a TeX programming exercise. As a game, it will solve the towers with (up to) 15 discs.

Instead of having to transform the common source into program or documentation, the central idea was to develop a method to have one common source which can be interpreted by a Prolog system as well as by LaTeX.

The basic operations (addition, subtraction, multiplication, division, power to an integer) are implemented by TeX macros in this package. Operands may be numbers with arbitrary numbers of digits; scientific notation is allowed. The expression scanner is also provided.

The package defines commands that create macros for typesetting vectors, matrices and functions, in a logical way. For example, logical indexing can then be used to refer to elements or arguments without hard-coding the symbols in the document.

The package contains commands for students and teachers of introductory physics. Commands for physical quantities intelligently handle SI units so the user need not do so. There are other features that should make LaTeX easy for introductory physics students.

The EMISA LaTeX package is provided for preparing manuscripts for submission to EMISA, and for preparing accepted submissions for publication as well as for typesetting the final document by the editorial office.

This package provides a LaTeX environment numcases to produce multi-case equations with a separate equation number for each case. There is also a subnumcases environment which numbers each case with the overall equation number plus a letter.

The package defines the \efbox command, which creates a box just wide enough to hold the text created by its argument. The command optionally puts a (possibly partial) frame around the box, and allows setting the box background colour.

This package provides a cult Greek font from the eighties, used at the University of Crete, Greece. It belonged to the first TeX installation in a Greek University and most probably the first TeX installation that supported the Greek language.

The package provides virtual fonts and LaTeX support files for mathematical calligraphic fonts based on the rsfs Adobe Type 1 fonts, with the slant substantially reduced. The output is quite similar to that from the Adobe Mathematical Pi script font.

These are the Computer Modern fonts extended with Russian letters, in Metafont sources and ATM Compatible Type 1 format. The fonts are provided in KOI-7, but virtual fonts are available to recode them to three other Russian 8-bit encodings.

With pxpic you draw pictures pixel by pixel. It was inspired by a lovely post by Paulo Cereda, among other things (most notably a beautiful duck) showcasing the use of characters from the Mario video games by Nintendo in LaTeX.

This package is a rewrite of the multibibliography package providing multiple bibliographies with different sorting. The new version offers a number of citation commands, streamlines the creation of bibliographies, ensures compatibility with the natbib package, and provides other improvements.

The macros enable the user to draw simple circuit diagrams in the picture environment, with no need of special resources. The macros are appropriate for drawing for school materials. The circuit symbols accord to the various parts of the standard IEC 617.
