使用向量中的元素顺序调用函数

您可以map用来实现它。

我在这里使用lambda表达式来定义一个仅接受一个参数的函数。

(defn f [x y ] (...) )
// apply f x y to every element of xs 
// in order to do this we need a function which takes only one argument the x_i and takes the second argument from somehere else - the second argument of g 
// that's what the lambda \x -> f x y does - in short form.
(defn g [xs y] (map (fn [x] (f x y)) xs))

例如

(def X [1 2 3 4])
(defn f [x y] (* x y))
(g X 3)
;=> (3 6 9 12)
