clock
command, this function computes
the epoch time, i.e, the time in seconds since January 1,1970
at 00:00:00 UTC. This function is most useful for calculating elapsed
times using the clock, and should be accurate to less than a millisecond
(although the true accuracy depends on accuracy of the argument vector).
The usage for clocktotime
is
y = clocktotime(x)
where x
must be in the form of the output of clock
, that is
x = [year month day hour minute seconds]
clocktotime
to time a delay of 1 second
--> x = clock x = 1.0e+03 * 2.0080 0.0030 0.0170 0 0.0430 0.0424 --> sleep(1) --> y = clock y = 1.0e+03 * 2.0080 0.0030 0.0170 0 0.0430 0.0434 --> clocktotime(y) - clocktotime(x) ans = 1.0010 --> quit
