The check suite for Eigen has been run from several compilers to be certain trustworthiness.

FloatX

FloatX, or Float Prolonged, is a header-only library for low-precision, floating level form emulation. Although natively appropriate with C++ compilers, FloatX can be named by other languages these as Python or Fortran. Floating position forms are extended further than the native single and double precision varieties. Template styles are provided that let the person to pick the quantity of bits applied for the exponent as very well as sizeable parts of the floating stage quantity. FloatX is based mostly on the strategy of the FlexFloat library for emulating decreased-precision floating styles, but implements a superset of FlexFloat features in C and gives C++ wrappers. FloatX emerged from the Open up Transprecision Computing initiative. It is obtainable cost-free underneath the Apache License 2.. 

OpenCV

OpenCV, or Open Supply Computer system Eyesight Library, is a computer system vision and device studying library created natively in C++, and out there less than an Apache 2 license. OpenCV was built to deliver widespread infrastructure for personal computer vision apps and speed up the use of device notion in business merchandise. Far more than 2,500 optimized algorithms for confront recognition, item detection, object classification, 3D product extraction, graphic lookup, and considerably extra, OpenCV has amassed a person group of much more than 47,000 people. Readily available from the OpenCV venture internet site, the library presents C++, Java, Python, and Matlab interfaces and supports Home windows, Linux, Android, and MacOS. CUDA and OpenCL interfaces are in growth.

Poco C++ Libraries

Intended to simplify C++ enhancement, the Poco (Portable Elements) C++ Libraries are cross-platform C++ libraries for setting up World-wide-web and community apps to operate on methods ranging from desktops and servers to cell and IoT equipment. The libraries also can be utilized to establish microservices with Rest APIs for equipment mastering or facts analytics. The Poco libraries are identical in notion to the Java Course Library, Microsoft’s .Web Framework, or Apple Cocoa.

Builders can use Poco libraries to create software servers in C++ that speak to SQL databases, Redis, or MongoDB, or to build program for IoT products that chat to cloud back again-ends. Among the capabilities of the libraries are a cache framework, HTML kind dealing with, an FTP consumer for transferring information, and an HTTP server and client. The Poco libraries are available no cost underneath the Improve Software License and downloadable from GitHub

Velox

Velox is an embeddable, vectorized execution library for OLAP devices. The library is meant to improve details processing programs and query engines. The venture was started as an inside engineering job at Facebook in 2020 and then open up sourced. In common utilization eventualities, Velox normally takes a thoroughly optimized query approach as input and performs the explained computation. Parts consist of a higher-amount typing method, a columnar memory module, perform packages, and community serializers. Velox is obtainable on GitHub in the Fb Incubator repo.

Windows Template Library

Originally from Microsoft, the Windows Template Library (WTL) is (due to the fact 2004) an open resource library for constructing light-weight Home windows apps and UI factors. Positioned as an alternative to the Microsoft Basis Courses toolkit, WTL extends ATL and delivers a established of courses for controls, dialogs, body home windows, and GDI objects.

Wt

Wt is a website GUI library in modern-day C++ that will allow builders to develop interactive website UIs with widgets, without getting to produce JavaScript. A server-aspect answer, Wt does request handling and web page rendering, delivering designed-in safety, PDF rendering, a 2D and 3D painting process, an object-relational mapping library, a charting library, and an authentication framework.
