Detailed Description

Class implementig interface to SuperLU_MT solver. Dependencies: iml module required (CompCol) Note: There is a conflict in include file (set.h) as defined by libstdc and superlu_mt 3.1. Therefore it is assumed that superlu include files are included using #include "SUPERLU_MT/include". The ${SUPERLU_MT_DIR} is added into compiler include path. The SUPERLU_MT/include has to be manually added pointing to ${SUPERLU_MT__DIR}/src directory
