matlab很常用，下面是find()函数的所有用法：1、 b=find(a),a是一个矩阵,查询非零元素的位置，如果X是一个行向量，则返回一个行向量，否则，返回一个列向量。如果X全是零元素或者是空数组，则返回一个空数组，例子如下所示,也可以用b=find(a>2)，这句的意思是在a中找到比较2大的元素；2、b...
% MATLAB code for find the indices of % all the non-zero elements present in the 3-D array x = [1 9 0; 3 -1 0; 0 0 7] % find() will get the indices of the elements % and the vector will store all the non-zero elements [row,col,v] = find(x) 输出: 总结 现在的专业软...
matlab find函数使用语法 find 找到非零元素的索引和值 语法: 1. ind = find(X) 2. ind = find(X, k) 3. ind = find(X, k, 'first') 4. ind = find(X, k, 'last') 5. [row,col] = find(X, ...) 6. [row,col,v] = find(X, ...) 说明: 1. ind = find(X) 找出矩阵X中...

matlab中 find()函数⽤法 ⼀、 功能: 寻找⾮零元素的索引和值 ⼆、相关函数语法: 1. ind = find(X) 2. ind = find(X, k) 3. ind = find(X, k, 'first') 4. ind = find(X, k, 'last') 5. [row,col] = find(X, ...) 6. [row,col,v] = find(X, ...) 三、说明: ...
k= find(X,n,direction), 如果方向为 "last", 则查找与 x 中的非零元素对应的最后 n 个索引。directionis "first" 的默认值, 它查找与非零元素对应的第一个 n 索引。 例子: Last Several Nonzero Elements Create a 6-by-6 magic square matrix with all of the odd-indexed elements equal to zero...
which allows for these types of operations on matrices, vectors, and multidimensional arrays.
Step 2:Then, we use a find statement with proper syntax to find indices and values of the nonzero element. Examples of Matlab find Index Given below are the examples of Matlab find Index: ADVERTISEMENT Data Science PRO 4655+ Hours of HD Videos | 80+ Learning Paths | 470+ Courses | 50...
