| LDL is a set of concise routines for factorizing symmetric |
| positive-definite sparse matrices, with some applicability to |
| symmetric indefinite matrices. Its primary purpose is to illustrate |
| much of the basic theory of sparse matrix algorithms in as concise a |
| code as possible, including an elegant new method of sparse symmetric |
| factorization that computes the factorization row-by-row but stores it |
| column-by-column. The entire symbolic and numeric factorization |
| consists of a total of only 49 lines of code. The package is written |
| in C, and includes a MATLAB interface. |
