%description
Some basic features of 'MUMPS' (Multifrontal Massively Parallel sparse
direct Solver) are wrapped in a class whose methods can be used for
sequentially solving a sparse linear system (symmetric or not) with one or
many right hand sides (dense or sparse). There is a possibility to do
separately symbolic analysis, LU (or LDL^t) factorization and system
solving. Third part ordering libraries are included and can be used:
'PORD', 'METIS', 'SCOTCH'. 'MUMPS' method was first described in Amestoy
et al. (2001) <doi:10.1137/S0895479899358194> and Amestoy et al. (2006)
<doi:10.1016/j.parco.2005.07.004>.
