+ CAMD p = camd (A), the approximate minimum degree ordering of A
+     P = CAMD (S) returns the approximate minimum degree permutation vector for
+     the sparse matrix C = S+S'.  The Cholesky factorization of C (P,P), or
+     S (P,P), tends to be sparser than that of C or S.  CAMD tends to be faster
+     than SYMMMD and SYMAMD, and tends to return better orderings than SYMMMD.
+     S must be square. If S is full, camd(S) is equivalent to camd(sparse(S)).
+ 
+     Usage:  P = camd (S) ;                   % finds the ordering
+             [P, Info] = camd (S,Control,C) ; % optional parameters & statistics
+             Control = camd ;                 % returns default parameters
+             camd ;                           % prints default parameters.
+ 
+        Control (1); If S is n-by-n, then rows/columns with more than
+            max (16, (Control (1))* sqrt(n)) entries in S+S' are considered
+            "dense", and ignored during ordering.  They are placed last in the
+            output permutation.  The default is 10.0 if Control is not present.
+        Control (2): If nonzero, then aggressive absorption is performed.
+            This is the default if Control is not present.
+        Control (3): If nonzero, print statistics about the ordering.
+ 
+        Info (1): status (0: ok, -1: out of memory, -2: matrix invalid)
+        Info (2): n = size (A,1)
+        Info (3): nnz (A)
+        Info (4): the symmetry of the matrix S (0.0 means purely unsymmetric,
+            1.0 means purely symmetric).  Computed as:
+            B = tril (S, -1) + triu (S, 1) ; symmetry = nnz (B & B') / nnz (B);
+        Info (5): nnz (diag (S))
+        Info (6): nnz in S+S', excluding the diagonal (= nnz (B+B'))
+        Info (7): number "dense" rows/columns in S+S'
+        Info (8): the amount of memory used by CAMD, in bytes
+        Info (9): the number of memory compactions performed by CAMD
+ 
+     The following statistics are slight upper bounds because of the
+     approximate degree in CAMD.  The bounds are looser if "dense" rows/columns
+     are ignored during ordering (Info (7) > 0).  The statistics are for a
+     subsequent factorization of the matrix C (P,P).  The LU factorization
+     statistics assume no pivoting.
+ 
+        Info (10): the number of nonzeros in L, excluding the diagonal
+        Info (11): the number of divide operations for LL', LDL', or LU
+        Info (12): the number of multiply-subtract pairs for LL' or LDL'
+        Info (13): the number of multiply-subtract pairs for LU
+        Info (14): the max # of nonzeros in any column of L (incl. diagonal)
+        Info (15:20): unused, reserved for future use
+ 
+     An assembly tree post-ordering is performed, which is typically the same
+     as an elimination tree post-ordering.  It is not always identical because
+     of the approximate degree update used, and because "dense" rows/columns
+     do not take part in the post-order.  It well-suited for a subsequent
+     "chol", however.  If you require a precise elimination tree post-ordering,
+     then do the following:
+ 
+     Example:
+        P = camd (S) ;
+        C = spones (S) + spones (S') ;  % skip this if S already symmetric
+        [ignore, Q] = etree (C (P,P)) ;
+        P = P (Q) ;
+ 
+     CAMD has the ability to order the matrix with constraints.  Each
+     node i in the graph (row/column i in the matrix) has a constraint,
+     C(i), which is in the range 1 to n.  All nodes with C(i) = 1 are
+     ordered first, followed by all nodes with constraint 2, and so on.
+     That is, C(P) is monotonically non-decreasing.  If C is not provided,
+     no constraints are used (the ordering will be similar to AMD's ordering,
+     except that the postordering is different).

+     See also AMD, COLMMD, COLAMD, COLPERM, SYMAMD, SYMMMD, SYMRCM.

- 
-  Tests CHOLMOD with various randomly-generated matrices, and the west0479
-  matrix distributed with MATLAB.  Random matrices are not good test cases,
-  but they are easily generated.  It also compares CHOLMOD and MATLAB on the
-  sparse matrix problem used in the MATLAB BENCH command.
- 
-  See CHOLMOD/MATLAB/Test/test_all.m for a lengthy test using matrices from
-  the UF sparse matrix collection.

- CHOLMOD_DEMO: a demo for CHOLMOD
- 
-  Tests CHOLMOD with various randomly-generated matrices, and the west0479
-  matrix distributed with MATLAB.  Random matrices are not good test cases,
-  but they are easily generated.  It also compares CHOLMOD and MATLAB on the
-  sparse matrix problem used in the MATLAB BENCH command.
- 
-  See CHOLMOD/MATLAB/Test/test_all.m for a lengthy test using matrices from
-  the UF sparse matrix collection.

-% This code can be quite easily adapted to estimate the 1-norm of any

-% computation of E (and E') times a vector is easy.  In this case, our matrix
-% of interest is:
-%

-%
-% That is, L*U is the LU factorization of A, where A, L and U
-% are sparse.  This code works for dense matrices A and L too,
-% but it would not be needed in that case, since E is easy to compute
-% explicitly.  For sparse A, L, and U, computing E explicitly would be quite

-%
-% Usage:
-%
-%       rho = lu_normest (A, L, U)
-%
-% which estimates the computation of the 1-norm:
-%
-%       rho = norm (A-L*U, 1)

-% Authors:  William W. Hager, Math Dept., Univ. of Florida
-%       Timothy A. Davis, CISE Dept., Univ. of Florida
-%       Gainesville, FL, 32611, USA.
-%       based on normest1, contributed on November, 1997
-%
-% This code can be quite easily adapted to estimate the 1-norm of any 
-% matrix E, where E itself is dense or not explicitly represented, but the
-% computation of E (and E') times a vector is easy.  In this case, our matrix
-% of interest is:
-%
-%       E = A-L*U
-%
-% That is, L*U is the LU factorization of A, where A, L and U
-% are sparse.  This code works for dense matrices A and L too,
-% but it would not be needed in that case, since E is easy to compute
-% explicitly.  For sparse A, L, and U, computing E explicitly would be quite
-% expensive, and thus normest (A-L*U) would be prohibitive.
-%
-% The three places that the matrix-vector multiply E*x is used are highlighted.
-% Note that E is never formed explicity.
-%
-% Written for MATLAB 4.2c and following.

-%   C = CONDEST(A,T) changes T, a positive integer parameter equal to

-%NORMEST1 Estimate of 1-norm of matrix by block 1-norm power method.
-%   C = NORMEST1(A) returns an estimate C of norm(A,1), where A is N-by-N.
-%   A can be an explicit matrix or a function AFUN such that
-%   FEVAL(@AFUN,FLAG,X) for the following values of
-%     FLAG       returns
-%     'dim'      N
-%     'real'     1 if A is real, 0 otherwise
-%     'notransp' A*X
-%     'transp'   A'*X
-%
-%   C = NORMEST1(A,T) changes the number of columns in the iteration matrix
-%   from the default 2.  Choosing T <= N/4 is recommended, otherwise it should
-%   be cheaper to form the norm exactly from the elements of A, as is done
-%   when N <= 4 or T == N.  If T < 0 then ABS(T) columns are used and trace
-%   information is printed.  If T is given as the empty matrix ([]) then the
-%   default T is used.
-%
-%   C = NORMEST1(A,T,X0) specifies a starting matrix X0 with columns of unit
-%   1-norm and by default is random for T > 1.  If X0 is given as the empty
-%   matrix ([]) then the default X0 is used.
-%
-%   C = NORMEST1(AFUN,T,X0,P1,P2,...) passes extra inputs P1,P2,... to
-%   FEVAL(@AFUN,FLAG,X,P1,P2,...).
-%
-%   [C,V] = NORMEST1(A,...) and [C,V,W] = NORMEST1(A,...) also return vectors
-%   V and W such that W = A*V and NORM(W,1) = C*NORM(V,1).
-%
-%   [C,V,W,IT] = NORMEST1(A,...) also returns a vector IT such that
-%   IT(1) is the number of iterations,
-%   IT(2) is the number of products of N-by-N by N-by-T matrices.
-%   On average, IT(2) = 4.
