C++ provides the functionality to find an element in the given range of elements in a vector. This is done by the find() function which basically returns an iterator to the first element in the range of vector elements [first, last) on comparing the elements equals to the val (value to ...
假设有一个int型的vector对象,名为vec,我们想知道其中是否包含某个特定值。 解决这个问题最简单的方法时使用标准库提供的find运算: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 1 // value we'll look for 2 int search_value = 42; 3 4 //call find to see if that value is present 5 vector...
I am trying to find the corresponding y values to a x vector, which is x=[-2:0.5:16.5], but my code is not giving me back a list of y values. It is just displaying that y =0 Here's my code: functionfindingy = findingy(x) ...
Syntax pks = findpeaks(y) [pks,locs] = findpeaks(y) [pks,locs,w,p] = findpeaks(y) [___] = findpeaks(y,x) [___] = findpeaks(y,Fs) [___] = findpeaks(___,Name,Value) findpeaks(___)Description pks = findpeaks(y) returns a vector with the local maxima (peaks) of the ...
const T& value 参数 : 要查找的元素 ; 返回值解析 : 返回 一个布尔值 , 表示 是否找到指定元素 ; 如果 找到 指定的元素 , 则返回 布尔值 true , 也就是 1 ; 如果 没有找到 指定的元素 , 则返回 布尔值 false , 也就是 0 ; 2、二分查找时间复杂度分析 二分查找 是 在已排序的数组中查找特定...

The simplest solution is to use the std::find algorithm defined in the <algorithm> header. The idea is to get the index using std::distance on the iterator returned by std::find, which points to the found value. We can also apply pointer arithmetic to the iterators. Therefore, the - ...
