Hi Jinzhu,
1. GluCat needs to obtain the inverse matrix and does so by using lu_factorize 
and lu_substitute with a right hand side which is a unit matrix of the 
appropriate size. You can see the code in the routine operator/ at
http://glucat.cvs.sourceforge.net/glucat/glucat/glucat/matrix_multi_imp.h?view=markup

For an example which is more relevant to your case, see

2. Sorry can't help.
Best, Paul
