spsolve

This crate defines a Solver trait for solving sparse systems of linear equations of the form:

    Ax = b

The trait is implemented using various open source libraries. They can be enabled using their associated feature. The following solvers are currently supported:

• CSparse (C, LGPL)
• BasicLU (C, MIT)
• KLU (C, LGPL)
• RLU (Rust, BSD)
• LUFact (Fortran, Apache/MIT)
• RSparse (Rust, MIT (LGPL?))

A benchmark for comparing solver performance is included. Test matrix data can be accessed by enabling the matrix feature. Solvers can be profiled using cpuprofiler and pprof.
