The package offers a collection of useful macros for disciplines related to signal processing. It defines macros for plotting a sequence of numbers, drawing the pole-zero diagram of a system, shading the region of convergence, creating an adder or a multiplier node, placing a framed node at a given coordinate, creating an up-sampler or a down-sampler node, drawing the block diagram of a system, drawing adaptive systems, sequentially connecting a list of nodes, and connecting a list of nodes using any node-connecting macro.

The examz document class builds on the exam document class. An author may use the class exactly as the exam class, but there are also additional features. The document class facilitates the writing of questions with random elements, the creation of multiple versions of an exam, and the use of separate files as question banks.

The horoscop package provides a unified interface for astrological font packages; typesetting with pict2e of standard wheel charts and some variations, in PostScript- and PDF-generating TeX engines; and access to external calculation software (Astrolog and Swiss Ephemeris) for computing object positions.

This is a fairly complete BibLaTeX style (citations and references) for APA (American Psychological Association) publications. It implements and automates most of the guidelines in the APA 7th edition style guide for citations and references.

This package provides the binaries for texlive-ptex.

The class may be used to typeset articles to be published in the proceedings of SAS(R) User group conferences and workshops. The layout produced by the class is based on that published by SAS Institute (2021).

The standard letter class letter has a label feature. You can activate it using \makelabels. While in Germany window envelopes are common, printing labels is not common, and scrlttr2 has never supported label printing. Using makelabels.lco does implement a \makelabels feature similar to the standard letter classes. Currently there are (almost) no configuration features for makelabels.lco. But you may use the envlab package after loading makelabels.lco to get various configuration features.

This PSTricks package facilitates the drawing of protractors, rulers, compasses and pencils.

The package provides two macros that produce representations of a swimmer's performances. The user records data in a text file and specifies as arguments of the macros the date range of interest. The macros extract the relevant information from the file and process it: \swimgraph produces a graph of the times in a single swimming event (specified as an argument), plotting long course and short course times in separate lines. Records and qualifying times, stored in text files, may optionally be included on the graph. \swimtext produces a written record of the times in all events. Files of current world and Canadian records are included.

This package provides \VerbatimCopy{in}{out} that will enable LaTeX to take a verbatim copy of one text file, and save it under another name. The package provides a means to specify the output directory to be used, but does no checking and may therefore overwrite an important file if used injudiciously.

This package provides macros, and some documentation, for typesetting papers for submission to journals published by the National Research Council Research Press. At present, only nrc2.cls (for two-column layout) should be used.

The package provides basic arithmetic operations to 8 decimal places for plain TeX or LaTeX. Results are exact when they fit within the digit limits. Along with the basic package is an optional extension that adds computation of sin, cos, log, sqrt, exp, powers and angles. These are also exact when theoretically possible and are otherwise accurate to at least 7 decimal places. In addition, the package provides a stack-based programming environment.

This is a collection of packages for LuaTeX, a TeX engine using Lua as an embedded scripting and extension language, with native support for Unicode, OpenType/TrueType fonts, and both PDF and DVI output. The LuaTeX engine itself, and plain formats, are in collection-basic.

This package provides macros to read and compare the modification dates of files. The files may be .tex files, images or other files (as long as they can be found by LaTeX). It uses the \pdffilemoddate primitive of pdfLaTeX to find the file modification date as PDF date string, parses the string and returns the value to the user. The package will also work for DVI output with recent versions of the LaTeX compiler which uses pdfLaTeX in DVI mode. The functionality is provided by purely expandable macros or by faster but non-expandable ones.

The package enables authors to designate in the preamble to make the document body enclosed with the given pieces of code. As is known, there are already various mechanisms provided by LaTeX kernel or packages that attach hooks at the beginning and end of documents.

This LaTeX package uses pgfkeys to retrieve individual data points generated in some script. Analogous to how one might generate graphics in a script and import those graphics into a LaTeX document.

tikzcodeblocks is a LaTeX package for typesetting blockwise graphic programming languages like Scratch, NEPO or PXT.

The package provides the means for LaTeX to implement a grid system as known from CSS grid systems. The facility is useful for creating box layouts as used in brochures.

The package extends the LaTeX labelling system: whenever a label is set, the values of counters (selected by the user) are recorded, along with the label. The value of these counters can be recalled with a command similar to \pageref.

The package also adds commands \sNAMEref (for each counter NAME that the user has selected); these commands display something only if the value of the NAME counter is changed from when the label was set. Many commands are provided to serve as a macro programming environment for using the extended labels.

This package provides commands that make it easy to highlight terms in equations and add annotation labels using TikZ. It should work with pdfLaTeX as well as LuaLaTeX.

The Nimbus 2015 Core fonts added Greek and Cyrillic glyphs. This package may be best suited as an add-on to the comprehensive Times package, providing support for Greek and Cyrillic. A new intermediate weight of NimbusMono (AKA Courier) is provided, along with a narrower version which may be useful for rendering code.

This package recreates some AmongUs characters in TikZ environments. Some interesting uses alongside other packages are also supported.

This font is designed for Arabic-based writing systems in the Kano region of Nigeria and Niger.

This package provides a japanese option for the Babel package. It defines all the language definition macros in Japanese. Currently this package works with pLaTeX, upLaTeX, XeLaTeX and LuaLaTeX.
