1251 the @var{k}-th super-diagonal. If it is negative, it is placed on the\n\ | |

5926 Return the CPU time used by your Octave session. The first output is\n\ | |
5927 the total time spent executing your process and is equal to the sum of\n\ | |
5928 second and third outputs, which are the number of CPU seconds spent\n\ | |
5929 executing in user mode and the number of CPU seconds spent executing in\n\ | |
5930 system mode, respectively. If your system does not have a way to report\n\ | |
5931 CPU time usage, @code{cputime} returns 0 for each of its output values.\n\ | |
5932 Note that because Octave used some CPU time to start, it is reasonable\n\ | |
