typedef struct { double fill; /* expected fill; nonzeros in factored matrix/nonzeros in original matrix */ double dtcol; /* tolerance for pivoting; pivot if off_diagonal*dtcol > diagonal */ double damping; /* scaling of identity added to matrix to prevent zero pivots */ double damp; /* if this is 1.0 and factorization fails, damp until successful */ } MatLUInfo;In Fortran these are simply double precision arrays of size MAT_LUINFO_SIZE
Notes: These are not usually directly used by users, instead use the PC type of LU All entries are double precision.
