How to figure out the amount of time my code has taken in ocaml? are there any functions to measure that?

推荐答案

如果要测量各个函数的执行时间，此实用程序函数在许多情况下会很有帮助:

If you want to measure execution time of individual functions, this utility function is helpful in many cases:

let time f x =
    let t = Sys.time() in
    let fx = f x in
    Printf.printf "Execution time: %fs\n" (Sys.time() -. t);
    fx

其中f是任何以x作为参数并返回内容的函数.

where f is any function which takes x as the argument and returns something.
