Purpose
symbfact() performs a symbolic factorization on matrix A and sets up the nonzero data structures which are suitable for supernodal Gaussian elimination with no pivoting (GENP). This routine features: o depth-first search (DFS) o supernodes o symmetric structure pruning
Return value
< 0, number of bytes needed for LSUB. = 0, matrix dimension is 1.0, number of bytes allocated when out of memory.
