How to measure execution time of each loop step in Julia?

I have a custom function and I would like to evaluate its media performance. For this, I would like to loop by executing my function a certain number of times. I want to do this because I see that the runtime is very unstable.

A typical execution measuring the execution time would look something like this

@time my_function()

or

@time begin
my_function()
end

In this particular case, I only visualize the execution time, but I don't know how to register the execution time to allocate the time for each iteration in a vector. For example, I would like something like this

vector_time = 1:100
for i in 1:100
    @time my_function()
    vector_time[i] = get_time_i # register the time of the i-th iteration 
end

If you are timing multiple sections of your code at once, you can also use TimerOutputs.jl, which I've found to be very convenient. It automatically computes average runtimes and % total runtime.

Try @elapsed instead to get the execution time in seconds.
