6002 Return the CPU time used by your Octave session. The first output is\n\ | |
6003 the total time spent executing your process and is equal to the sum of\n\ | |
6004 second and third outputs, which are the number of CPU seconds spent\n\ | |
6005 executing in user mode and the number of CPU seconds spent executing in\n\ | |
6006 system mode, respectively. If your system does not have a way to report\n\ | |
6007 CPU time usage, @code{cputime} returns 0 for each of its output values.\n\ | |
6008 Note that because Octave used some CPU time to start, it is reasonable\n\ | |
6009 to check to see if @code{cputime} works by checking to see if the total\n\ | |
6010 CPU time used is nonzero.\n\ | |
