The explicit specifier may only appear within the decl-specifier-seq of the declaration of a constructor or conversion function(since C++11) within its class definition.
因此,当打印变量a时,它虽存在于函数体(因为a已经被声明),但仍然是undefined。
So, at the time the variable a is printed, it exists in the function(it's declared) but it's still undefined.
你可以使用定义于函数之外的变量的值(假设函数中没有具有相同名字的变量)。
You can use the values of such variables defined outside the function(assuming there is no variable with the same name within the function)..
在经典数学中,傅里叶变换用于将函数(如波信号)转换为组成频率。
In classical mathematics, a Fourier transform is used to turn a function(like a wave signal) into its constituent frequencies.
因此,无论是哪种情况,我们都可以建立一个新的更狭窄的区间,用于搜索函数的最小值。
Thus, in either case, we can construct a new narrower search interval that is guaranteed to contain the function's minimum.
使用严格模式,只需要将'usestrict'置于函数体的顶部。
You invoke strict mode by putting the string“use strict” at the top of a function.
当一个用户定义的函数调用时,它的局部帧扩展于函数所关联的环境。
When a user-defined function is called, its local frame extends the environment associated with the function.
还有一些其他的区别,但是现在你可以认为方法就是类似于函数的东西。
There are some other differences, but for now, you can think of them as something similar to functions.
就像其他语言一样,这样可以让你大部分时间专注于函数调用(例如函数())和赋值(例如a=“b”)。
Just like other languages, focus on function calls(e.g. function()) and assignments(e.g. a<-“b”).
这是很重要的,部分是由于每一个光滑的多元函数的二阶表现,都由属于该函数的黑塞矩阵的二次型描述;.
This is important partly because the second-order behavior of every smooth multi-variable function is described by the quadratic form belonging to the function's Hessian;
For example in Rhino, for the[[Scope]] property of a function, corresponds a non-standard property__parent__ which we discussed in the chapter about variable object.
Defer并不仅仅限于函数(function)。
Defer is not restricted only to functions.
Joy-它是一种基于函数组合的纯函数式语言。
Joy: It is a purely functional language that is based on a composition of functions.
