Input matrix: 5-by- 5 with 14 entries
Column: 1 number of entries: 2 with row indices in AI ( 1 ... 2)
row indices: 1 2
Column: 2 number of entries: 4 with row indices in AI ( 3 ... 6)
row indices: 1 2 3 5

amd: approximate minimum degree ordering, results:
status: OK
n, dimension of A: 5
nz, number of nonzeros in A: 14
symmetry of A: 0.8889
number of nonzeros on diagonal: 5
nonzeros in pattern of A+A' (excl. diagonal): 10
# dense rows/columns of A+A': 0
memory used, in bytes: 228
# of memory compactions: 0
The following approximate statistics are for a subsequent
factorization of A(P,P) + A(P,P)'. They are slight upper
bounds if there are no dense rows/columns in A+A', and become
looser if dense rows/columns exist.
nonzeros in L (excluding diagonal): 5
nonzeros in L (including diagonal): 10
# divide operations for LDL' or LU: 5
# multiply-subtract operations for LDL': 6
# multiply-subtract operations for LU: 7
max nz. in any column of L (incl. diagonal): 3
chol flop count for real A, sqrt counted as 1 flop: 22
LDL' flop count for real A: 17
LDL' flop count for complex A: 93
LU flop count for real A (with no pivoting): 19
LU flop count for complex A (with no pivoting): 101
PERM ( 1) = 1
PERM ( 2) = 4
PERM ( 3) = 3
