# 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)
- 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](github.com/google/pprof).
