如何添加在F＃两个数值数组 [英] How do I add two numeric arrays in F#

问题描述

我完全新的F＃。我已搜查高和低，但我找不到我想要的一个例子。

 让A = [| 1.0，2.0，3.0，4.0 |] ;; //也许用分隔符;
让B = [| 4.0，3.5，2.5，0.5 |];让C = A + B ;; //我怎么定义数组的加法运算符？
//预计C = [| 5.0，5.5，5.5，4.5 |]
 

我已经接近与这发布，但它不是我想要的。

解决方案

 让内联（++）A B = Array.map2（+）A B让A = [| 1.0; 2.0; 3.0; 4.0 |] ;;
让B = [| 4.0; 3.5; 2.5; 0.5 |] ;;
让A1 = [| 1; 2; 3; 1 |] ;;
让B1 = [| 4; 3; 2; 1 |] ;;让C = A +乙
让C1 = A1 + B1
 

I am totally new to F#. I have searched high and low but I cannot find an example for what I want.

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 |]

I have come close with this posting, but it is not what I want.

解决方案

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
