Sorry I forgot to reply. Did you find where to look for the {L, U} data structures?

It doesn't matter, I first tried to output the matrix of row and column permutation later, which I could do, but when it came to symbolic decomposition, I was confused by Etree and Supernode. Although I looked at {L, U}data structures, the structure of the inside puzzled me, I still couldn't find a correct way to view the matrix after symbolic decomposition.Anyway, thank you for your letter～ At 2022-03-24 00:28:58, "X.

Section 2.3 of the Users Guide explains various matrix structures, with a small example:

In SRC/dutil.c, there are several print routines to print the matrices, e.g., dPrint_SuperNode_Matrix()
