Matlab find values in array used for find indices and values of nonzero elements in the given array. To find values of nonzero elements in array, we need to take all elements in array and use proper syntax. The steps for find values of nonzero value using find values in array: ...
% 创建一个数组 array = [1, 2, 3, 4, 5, 4, 3, 2, 1]; % 查找数组中跟随特定值的元素 value = 4; indices = find(array == value); % 使用逻辑索引查找数组中跟随特定值的元素 logical_indices = array == value; % 输出结果 disp(find(logical_indices)); 输出结果与之前的示例相同...

k = find(X) k = find(X,n) k = find(X,n,direction) [row,col] = find(___) [row,col,v] = find(___) Description k= find(X)returns a vector containing thelinear indicesof each nonzero element in arrayX. IfXis a vector, thenfindreturns a vector with the same orientation asX...
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...
