what's the time of pause(1)

is this time equal 1 s??

Answer 1

[Paulo Silva]

pause(n) pauses execution for n seconds before continuing, where n can be any nonnegative real number. The resolution of the clock is platform specific. A fractional pause of 0.01 seconds should be supported on most platforms. Pausing must be enabled for this to take effect.

Try this:

tic,pause(1),toc

The elapsed time should be slightly over 1 second, due to calling the pause function and other overhead.

or using the profiler :)

Built-in functions don't show in the profiler... at least in 2007b.

Also, I have noticed that the profiler total time run per function, or even per line of code is completely useless. For example, when looking at the profile of running an M-file which I know took less than 2 seconds to run, I see it saying things like REPMAT took 3.5 seconds alone, and meshgrid took 2.8 seconds - rubbish!

I only look at the relative times run to get useful information.

I'm with the version 2008b and I can profile just the pause(1), it takes an average of 1.009 seconds, I'm also a fan of the tic and toc functions instead of the profiler
