% store it in the index index = find(array==2) 输出: 当数组包含重复值时,find()函数将打印相应元素的所有索引。因此,如果您不想要该元素的所有索引,则可以使用find(X,n)函数。 找到(X,n) 返回X 中元素的前 n 个索引。 例子: MATLAB % MATLAB code for return first % n
This MATLAB function returns an array of Stateflow API objects in the hierarchy of location that have a property called propertyName with a value of propertyValue.

matlab find函数用法是什么 简介 用法: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;b=find(a,2),找出a中最...
For example, to find signal line segments in a model named myModel that are trunks and look under masks, enter this command in the MATLAB Command Window. trunkSegments = find_system('myModel',FindAll = 'on',.. LookUnderMasks = 'all',type='line',SegmentType = 'trunk');...

This MATLAB function finds trends in a vector of data using singular spectrum analysis (SSA), which assumes an additive decomposition of the data such that A = LT+ST+R.
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 to right. For example, consider a 3-by-3 matrix. You can reference the A(2,2) ...
