Let us see an example related to find function, find function used to find indices and values of nonzero value. So in this example, we take a 3-by-3 matrix, and this matrix takes into a variable ‘Y’. So index 1 starts with row 1 and column one, and the next index value is 2...
for index = values <program statements> ... end 1. 2. 3. 4. 简单的实例: for a = 10:20 fprintf('value of a: %d \n', a); end 1. 2. 3. 输出结果为: value of a: 10 value of a: 11 value of a: 12 value of a: 13 value of a: 14 value of a: 15 value of a: 16 ...
Functioni = find_first(array, value) % FIND_FIRST Find first index of a value in an array. % I = FIND_FIRST(ARRAY, VALUE) returns the index I into the ARRAY where the % first occurrence of VALUE is found. If VALUE is not in ARRAY, then an error is raised. ...
ind = find(strcmp(names,'Charlie')); % strcmp接受向量的输入 返回Logical数组 % find紧接着找出逻辑数组中非零元素的Index numbers{ind} 其中第3行strcmp接受元胞作为输入,在其中寻找Charlie,find函数将返回Charlie所在的位置,这样的方式比使用for循环要快,但无一例外的是,两种方法都要从头开始遍历一个数组,终...
