Another timeit update

I just posted another timeit update to the MATLAB Central File Exchange. (See my original post on timeit for a detailed explanation of its purpose and use.) The new version has a few improvements:

  • Times very fast functions more accurately
  • Warns you when the reported time might be affected by time-measurement overhead
  • Takes less time to finish for functions that take more than a few seconds to run

Here's an example of the new warning message: 

>> timeit(@() sin(pi))
Warning: The measured time for F may be inaccurate because it is close to the
estimated time-measurement overhead (1.2e-006 seconds).  Try measuring something
that takes longer.
