+Syntax (for all versions: di, dl, zi, and zl):
+
+    #include "umfpack.h"
+    double stats [2] ;
+    umfpack_tic (stats) ;
+    ...
+    umfpack_toc (stats) ;
+
+Purpose:
+
+    umfpack_tic returns the CPU time and wall clock time used by the process.
+    The CPU time includes both "user" and "system" time (the latter is time
+    spent by the system on behalf of the process, and is thus charged to the
+    process).  umfpack_toc returns the CPU time and wall clock time since the
+    last call to umfpack_tic with the same stats array.
+
+    Typical usage:
+
+	umfpack_tic (stats) ;
+	... do some work ...
+	umfpack_toc (stats) ;
+
+    then stats [1] contains the time in seconds used by the code between
+    umfpack_tic and umfpack_toc, and stats [0] contains the wall clock time
+    elapsed between the umfpack_tic and umfpack_toc.  These two routines act
+    just like tic and toc in MATLAB, except that the both process time and
+    wall clock time are returned.
+
+    This routine normally uses the sysconf and times routines in the POSIX
+    standard.  If -DNPOSIX is defined at compile time, then the ANSI C clock
+    routine is used instead, and only the CPU time is returned (stats [0]
+    is set to zero).
+
+    umfpack_tic and umfpack_toc are the routines used internally in UMFPACK
+    to time the symbolic analysis, numerical factorization, and the forward/
+    backward solve.
+
+Arguments:
+
+    double stats [2]:
+
+	stats [0]:  wall clock time, in seconds
+	stats [1]:  CPU time, in seconds
