Suitesparse is a collection of libraries for computations involving
sparse matrices.
.
The LDL library provides routines for sparse LDL' factorization and solving.
These routines are not terrifically fast (they do not use dense matrix
kernels), but the code is very short and concise. The purpose is to illustrate
the algorithms in a very concise and readable manner, primarily for
educational purposes.
