Editing Cholesky decomposition (section)

===Computer code===
* [http://netlib.org/lapack/ LAPACK] is a collection of FORTRAN subroutines for solving dense linear algebra problems (DPOTRF, DPOTRF2, [http://www.netlib.org/utk/papers/factor/node9.html details] [http://www.netlib.org/utk/papers/factor/node13.html performance])
* [http://www.alglib.net/ ALGLIB] includes a partial port of the LAPACK to C++, C#, Delphi, Visual Basic, etc. (spdmatrixcholesky, hpdmatrixcholesky)
