The mattens package contains the definitions to typeset matrices, vectors and tensors as used in the engineering community for the representation of common vectors and tensors such as forces, velocities, moments of inertia, etc.

The package provides commands that display the value of a LaTeX counter in a variety of formats (ordinal, text, hexadecimal, decimal, octal, binary etc). The package offers some multilingual support; configurations for use in English (both British and American usage), French (including Belgian and Swiss variants), German, Italian, Portuguese and Spanish documents are provided.

Pst-coil is a PSTricks based package for coils and zigzags and for coil and zigzag node connections.

This package provides a collection of macros for French maths teachers in colleges and lycées (and perhaps elsewhere). It is hoped that the package will facilitate the everyday use of LaTeX by mathematics teachers.

This package allows to slant (or shear) short pieces of text to the left or to the right by an arbitrary angle, thus creating for example ``fake italics'' or upright italics. Several back-ends that do the actual shearing are supported, though currently the pdfLaTeX back-end works best concerning output quality and processing speed.

The package uses PSTricks to draw bar charts from data stored in a comma-delimited file. Several types of bar charts may be drawn, and the drawing parameters are highly customizable.

Catppuccin is a nice pastel theme in four flavors (Latte, Frappe, Macchiato, Mocha).

This simple package defines a greek environment to be used with pdfLaTeX only, that accepts an optional Greek font family name to type its contents with. A similar \greektxt command does a similar action for shorter texts.

This package provides additional facilities in a picture environment for drawing linear, cubic, and rational quadratic Bezier curves (standard LaTeX only offers non-rational quadratic splines). It also ships with the LaTeX package multiply that provides a command for multiplication of a length without numerical overflow.

The aim of this LaTeX package is to provide a complete as possible list of common Unicode symbols with their translations to LaTeX code. This is useful in the development of templates which are intended to work with modern TeX engines (LuaTeX, XeTeX) as well as traditional ones (TeX, pdfTeX).

The package provides a simple, though fancy float environment to document terminal sessions --- like command executions or shell operations. The look and feel of the package output imitates the look of a shell prompt.

The hep-title package extends the title macros of the standard classes with macros for a preprint, affiliation, editors, and endorsers.

The package facilitates the formatting of currencies (amounts and units) with various formatting capabilities.

The package is a small set of macros for drawing direction fields, phase portraits and trajectories of differential equations and two dimensional autonomous systems. The Euler, Runge-Kutta and fourth order Runge-Kutta algorithms are available to solve the ODEs. The picture is translated into mfpic macros and MetaPost is used to create the final drawing.

The package provides macros for command definition that save the name of the command being defined in a file or a macro container. The list could be useful for spelling exceptions in text editors that do not support TeX syntax.

This package allows the drawing of vectorian ornaments (196) with PGF/TikZ.

This package defines the command \perfectcut#1#2 which displays a bracket <#1||#2>. Various other delimiters are similarly defined (parentheses, square brackets ...). The effect of these commands is to let the delimiters grow according to the number of nested \perfectcommands (regardless of the size of the contents).

The package was originally intended for solving a notational issue for direct-style continuation calculi in proof theory. For general use, the package also defines commands for defining other sorts of delimiters which will behave in the same way. The package also offers a robust reimplementation of \big, \bigg, etc.

The package supports typesetting documents whose counters are represented in base twelve, also called dozenal. It includes a macro for converting positive whole numbers to dozenal from decimal (base ten) representation. The package also includes a few other macros and redefines all the standard counters to produce dozenal output. Fonts, in Roman, italic, slanted, and boldface versions, provide ten and eleven. The fonts were designed to blend well with the Computer Modern fonts, and are available both as Metafont source and in Adobe Type 1 format.

This package provides a Finnish language module for glossaries package.

The l3build module is designed to support the development of high-quality LaTeX code by providing: a unit testing system, automated typesetting of code sources, and a reliable packaging system for CTAN releases. The bundle consists of a Lua script to run the tasks and a .tex file which provides the testing environment.

The package is based on the icomma package, and intended as a solution for situations where the text comma character discerns from the math comma character, e.g., when fonts without math support are involved. Escaping to text mode every time a comma is used in math mode may slow down the compilation process.

Visual help for PSTricks based on images with minimum text, one image per command or per parameter.

The gauss package provides configurable tools for producing row and column operations on matrices (a.k.a.: Gaussian operations).

multidef provides a simple way of defining several macros having similar definitions.
