Elapsed + allocated?

General Usage Performance
1

I am familiar with the @elapsed and @allocated functions that allow me to save as a variable either the elapsed time and allocated memory during a function run (respectively). Is there a method that will return both variables at once so they can both be saved to variables? Thanks!

Try @timed

Thank you! That was so simple but I’m a beginner at Julia and couldn’t find it.

That’s what help forums like this are for sometimes! (Also sometimes for more complex problems) Welcome. :slight_smile:

It’s definitely not a foolproof method, but the See also part of the documentation (type ? in the REPL) is often useful:

help?> @elapsed
  @elapsed

  A macro to evaluate an expression, discarding the resulting value, instead returning the number of seconds it took
  to execute as a floating-point number.

  In some cases the system will look inside the @elapsed expression and compile some of the called code before
  execution of the top-level expression begins. When that happens, some compilation time will not be counted. To
  include this time you can run @elapsed @eval ....

  See also @time, @timev, @timed, @allocated, and @allocations.

  julia> @elapsed sleep(0.3)
  0.301391426

leading you to @timed.
