Detailed Description

header file containing the templated implementation of matrix inversion routines for use with ROOT's SMatrix classes (symmetric positive definite case)

Author:

Manuel Schiller

Date:

Aug 29 2008 initial release inside LHCb

May 7 2009 factored code to provide a nice Cholesky decomposition class, along with separate methods for solving a single linear system and to obtain the inverse matrix from the decomposition
