在MATLAB中,可以使用find()函数来查找小数。find()函数用于查找数组中满足特定条件的元素的索引。 要在MATLAB中使用find()函数查找小数,可以按照以下步骤进行操作: 1. 创...

Finding the largest number recursively requires us to call the function from with in the function. In the first call we pass the complete array, index of last element and largest element (initialised to the first element of the array). In search recursion call, we compare the current largest...

const f=arr.filter(item=>item%2===0);//返回偶数console.log(f);//[6, 10, 100]console.log(arr);//[1,6,9,10,100,25] 4. map() 可以逐个改变数组 创建并返回一个新数组(==不改变原数组==) 语法:let newArray = oldArray.map((item, index, arr) => {}) item当前元素、index当前索...

We can also implement our custom function to return the index of the first occurrence of the specified element in an array. The idea is to perform a linear search on the array using a regular for loop, and terminate the search on the first matching item. If the array is sorted, we ...
