LinearSolve.jl: High-Performance Unified Linear Solvers
LinearSolve.jl is a unified interface for the linear solving packages of Julia. It interfaces with other packages of the Julia ecosystem to make it easy to test alternative solver packages and pass small types to control algorithm swapping. It also interfaces with the ModelingToolkit.jl world of symbolic modeling to allow for automatically generating high-performance code.
Performance is key: the current methods are made to be highly performant on scalar and statically sized small problems, with options for large-scale systems. If you run into any performance issues, please file an issue.
Installation
To install LinearSolve.jl, use the Julia package manager:
using Pkg
Pkg.add("LinearSolve")Contributing

Roadmap
Wrappers for every linear solver in the Julia language is on the roadmap. If there are any important ones that are missing that you would like to see added, please open an issue. The current algorithms should support automatic differentiation. Pre-defined preconditioners would be a welcome addition.
