% find() will get the index of element % store it in the index index = find(array==2,2,'first') 输出: 示例2: MATLAB % array of integers array = [1 2 3 4 5 6 2 4 2] % find() will get the index of element % store it in the index index = find(array==2,2,'last') ...
MATLAB中的find函数用于在数组中查找满足指定条件的元素,并返回这些元素的索引。它的语法如下:indices = find(array) indices = find(array, k) indices = find(array, k, ‘first’) indices = find(array, k, ‘last’)其中,array是要查找的数组,可以是向量、矩阵或多维数组。k是可选参数,表示要查找的元...
element = A(index); 在这个例子中,我们创建了一个结构化矩阵A,其中包含了姓名和年龄两个字段。然后使用find函数查找年龄为30的元素的索引,并通过索引访问到该元素。 对于MATLAB中的结构化矩阵,可以使用这种方式来查找特定索引的元素,方便进行数据的检索和处理。 腾讯云相关产品和产品介绍链接地址: 腾讯云...
A linear index allows use of a single subscript to index into an array, such as A(k). MATLAB® treats the array as a single column vector with each column appended to the bottom of the previous column. Thus, linear indexing numbers the elements in the columns from top to bottom, left...
Find the nonzero elements in a 4-by-2-by-3 array. Specify two outputs,rowandcol, to return the row and column subscripts of the nonzero elements. When the input is a multidimensional array (N > 2),findreturnscolas a linear index over theN-1trailing dimensions ofX. ...
其中ind1保存行号,ind2保存列号,注意对于matlab而言矩阵的第一个元素为第1行第1列。 如果我们只需要保存列号那可以这么写 a=[1, 2, 5; 2, 8, 9; 3, 9, 6; 0, 5, 2]; [~,ind2]=find(a==2); 只保存行号也是同理,值得注意的是,如果这么写 ...
MATLAB Online에서 열기 I have an array of 1000+ samples. I want to find the index of nonzero elements in a large matrix in a shortest possible time. Whats the best way to get the list of indexing without using "find" funcion?
