PURPOSE - THIS ROUTINE PERFORMS SYMBOLIC FACTORIZATION
ON A PERMUTED LINEAR SYSTEM AND IT ALSO SETS UP THE
COMPRESSED DATA STRUCTURE FOR THE SYSTEM.
INPUT PARAMETERS -
NEQNS - NUMBER OF EQUATIONS.
(XADJ, ADJNCY) - THE ADJACENCY STRUCTURE.
(PERM, INVP) - THE PERMUTATION VECTOR AND ITS INVERSE.
UPDATED PARAMETERS -
MAXSUB - SIZE OF THE SUBSCRIPT ARRAY NZSUB. ON RETURN,
IT CONTAINS THE NUMBER OF SUBSCRIPTS USED
OUTPUT PARAMETERS -
XLNZ - INDEX INTO THE NONZERO STORAGE VECTOR LNZ.
(XNZSUB, NZSUB) - THE COMPRESSED SUBSCRIPT VECTORS. MAXLNZ - THE NUMBER OF NONZEROS FOUND.
