如何在F＃中添加两个数字数组

Question

我对F＃完全不熟悉。我搜索过高低，但我找不到我想要的例子。

let A = [| 1.0, 2.0, 3.0, 4.0 |];; //maybe delimiter with ;
let B = [| 4.0, 3.5, 2.5, 0.5 |];;

let C = A + B;; //how do I define the addition operator for arrays?
// expect C=[| 5.0, 5.5, 5.5, 4.5 |]

我已经接近发布了this，但这不是我想要的。

Answer 1

let inline (++) a b = Array.map2 (+) a b

let A = [| 1.0; 2.0; 3.0; 4.0 |];;
let B = [| 4.0; 3.5; 2.5; 0.5 |];;
let A1 = [| 1; 2; 3; 1 |];;
let B1 = [| 4; 3; 2; 1 |];;

let C = A ++ B
let C1 = A1 ++ B1
