typedef struct { double levels; /* ILU(levels) */ double fill; /* expected fill; nonzeros in factored matrix/nonzeros in original matrix*/ double diagonal_fill; /* force diagonal to fill in if initially not filled */ double dt; /* drop tolerance */ double dtcol; /* tolerance for pivoting */ double dtcount; /* maximum nonzeros to be allowed per row */ double damping; /* scaling of identity added to matrix to prevent zero pivots */ double damp; /* if is 1.0 and factorization fails, damp until successful */ } MatILUInfo;In Fortran these are simply double precision arrays of size MAT_ILUINFO_SIZE
Notes: These are not usually directly used by users, instead use the PC type of ILU All entries are double precision.
