Solving a system of linear equations is one of the most fundamental computational problems for many fields of mathematical studies, such as regression problems from statistics or numerical partial differential equations. Rlinsolve provides basic stationary iterative solvers such as Jacobi, Gauss-Seidel, Successive Over-Relaxation and SSOR methods. Nonstationary, also known as Krylov subspace methods are also provided. Sparse matrix computation is also supported in that solving large and sparse linear systems can be manageable using Matrix package along with RcppArmadillo. For a more detailed description, see a book by Saad (2003), doi:10.1137/1.9780898718003.

xeus enables custom kernel authors to implement Jupyter kernels more easily. It takes the burden of implementing the Jupyter Kernel protocol so developers can focus on implementing the interpreter part of the Kernel.

Rygel is a home media solution that allows you to easily share audio, video and pictures, and control of media player on your home network. In technical terms it is both a UPnP AV MediaServer and MediaRenderer implemented through a plug-in mechanism. Interoperability with other devices in the market is achieved by conformance to very strict requirements of DLNA and on the fly conversion of media to format that client devices are capable of handling.

A photogrammetry toolkit that provides improved methods for making and using camera models (calibration, tracking, mapping, etc). The focus is on calibration and uncertainty propagation to produce the most accurate models possible. This package provides the Python interfaces

Part of the Wayland project is also the Weston reference implementation of a Wayland compositor. Weston can run as an X client or under Linux KMS and ships with a few demo clients. The Weston compositor is a minimal and fast compositor and is suitable for many embedded and mobile use cases.

Opencl-clang is a thin wrapper library around clang. It has an OpenCL-oriented API and is capable of compiling OpenCL C kernels to SPIR-V modules.
