--------------------------------------------------------------------
the ILUMtx is used to compute, store and solve with a factorization
of the form A = (L+I)D(I+U), (U^T+I)D(I+U) or (U^H+I)D(I+U).
the factorization is very simple, stored by vectors, and can
be exact (up to roundoff) or approximate. it is a less
complicated alternative to the FrontMtx object.
neqns - # of equations
