KLU
KLU is a software library for solving sparse linear systems using LU factorization. It is designed to handle large, sparse matrices efficiently, with particular emphasis on the kinds of systems that arise in circuit simulation. KLU provides both the factorization of a sparse matrix and solutions for multiple right-hand sides, aiming to minimize memory usage and computation time.
The library is implemented in C and offers a C API, with optional interfaces for other languages.
KLU is part of the SuiteSparse collection of sparse matrix algorithms and tools. It was developed by
Availability and usage typically involve incorporating KLU into a software workflow that supplies a sparse matrix
