This Emacs mode enables interactive development with Agda. It also aids the input of Unicode characters.

The standard library aims to contain all the tools needed to write both programs and proofs easily. While we always try and write efficient code, we prioritize ease of proof over type-checking and normalization performance. If computational performance is important to you, then perhaps try agda-prelude instead.

A formalised, cross-linked reference resource for mathematics done in Homotopy Type Theory. Unlike the HoTT book, the 1lab is not a “linear” resource: Concepts are presented as a directed graph, with links indicating dependencies.

Zbarlight is a simple wrapper for the zbar library. It can read all zbar supported codes.

libdmtx is a software library that enables programs to read and write Data Matrix barcodes of the modern ECC200 variety. This package, dmtx-utils, provides command line utilities that allow scripts and command line users to use libdmtx functionality.

This package includes the following programs:

1. dmtxquery: Extract information from dmtxread output.

2. dmtxread: Scan Data Matrix barcodes.

3. dmtxwrite: Create Data Matrix barcodes.

ZBar can read barcodes from various sources, such as video streams, image files, and raw intensity sensors. It supports EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 93, Code 39, Codabar, Interleaved 2 of 5, QR Code and SQ Code. Included with the library are basic applications for decoding captured bar code images and using a video device (e.g. webcam) as a bar code scanner. For application developers, language bindings are included for C, C++ and Python as well as GUI widgets for GTK and Qt.

qrcodegen-cpp is a QR code generator library in C++. The project also offers Java, Javascript, Python, C, and Rust implementations.

Read one-dimensional barcodes and QR codes using the zbar library.

Features:

• Pure python

• Works with PIL / Pillow images, OpenCV / numpy ndarrays, and raw bytes

• Decodes locations of barcodes

• No dependencies, other than the zbar library itself

Libqrencode is a C library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and is highly robust.

libdmtx is software for reading and writing Data Matrix 2D barcodes of the modern ECC200 variety. libdmtx is a shared library, allowing C/C++ programs to use its capabilities without restrictions or overhead.

ZXing-CPP is a barcode scanning library.

Zint is a suite of programs to allow easy encoding of data in any of the wide range of public domain barcode standards and to allow integration of this capability into your own programs.

GNU Barcode is a flexible tool to produce printed barcodes from text strings. It supports a variety of encoding standards and sizing measurements. Barcodes can be output in PostScript or Encapsulated PostScript formats.

fpylll is a Python wrapper for fplll.

PARI/GP is a widely used computer algebra system designed for fast computations in number theory (factorisations, algebraic number theory, elliptic curves...), but it also contains a large number of other useful functions to compute with mathematical entities such as matrices, polynomials, power series, algebraic numbers, etc., and a lot of transcendental functions. PARI is also available as a C library to allow for faster computations.

The la4j library is a Java library that provides Linear Algebra primitives (matrices and vectors) and algorithms. The key features of the la4j library are:

• No dependencies and tiny size

• Fluent object-oriented/functional API

• Sparse (CRS, CCS) and dense (1D/2D arrays) matrices

• Linear systems solving (Gaussian, Jacobi, Zeidel, Square Root, Sweep and other)

• Matrices decomposition (Eigenvalues/Eigenvectors, SVD, QR, LU, Cholesky and other)

• MatrixMarket/CSV IO formats support for matrices and vectors

Spectra stands for Sparse Eigenvalue Computation Toolkit as a Redesigned ARPACK. It is a C++ library for large scale eigenvalue problems, built on top of Eigen. It is implemented as a header-only C++ library and can be easily embedded in C++ projects that require calculating eigenvalues of large matrices.

This package provides functions for 1D and 2D Discrete Cosine Transform (DCT), Discrete Sine Transform (DST) and Discrete Hartley Transform (DHT).

FLINT is a C library for number theory. It supports arithmetic with numbers, polynomials, power series and matrices over many base rings, including multiprecision integers and rationals, integers modulo n, p-adic numbers, finite fields (prime and non-prime order) and real and complex numbers (via the Arb extension library).

Operations that can be performed include conversions, arithmetic, GCDs, factoring, solving linear systems, and evaluating special functions. In addition, FLINT provides various low-level routines for fast arithmetic.

Symmetrica is a library for combinatorics. It has support for the representation theory of the symmetric group and related groups, combinatorics of tableaux, symmetric functions and polynomials, Schubert polynomials, and the representation theory of Hecke algebras of type A_n.

xtensor is a C++ library meant for numerical analysis with multi-dimensional array expressions.

xtensor provides:

• an extensible expression system enabling lazy broadcasting.

• an API following the idioms of the C++ standard library.

• tools to manipulate array expressions and build upon xtensor.

Normaliz is a tool for computations in affine monoids, vector configurations, rational polyhedra and rational cones. Normaliz now computes rational and algebraic polyhedra, i.e., polyhedra defined over real algebraic extensions of QQ.
