index = find(array==2,2,'last')输出：[行，列] = 查找（x）要在 3 维数组中查找元素的索引，您可以使用语法[row,col] = find(x)这将为您提供元素所在的行和列。例子：MATLAB % MATLAB code for Finding an index % of an element in a 3-D array array = [1 2 3; 4 5 6; 7 8 9]% ...
此文用来存个档,便于回顾。 由于matlab各版本部分语法存在差异,可能会出现bug,用help查帮助文档即可。 里面的一些内容仅供参考,知识量有限,仅供入门。 后期可能会随缘写一点笔记。 如果没有装Matlab,我这里有一篇建模软件的博客:https://www.cnblogs.com/cruelty_angel/p/10563509.html 变量名:字母数字串(第一个字...
In MATLAB, a vector is a one-dimensional array used to store a series of numerical values or data elements. Vectors can be represented as either row vectors or column vectors, where row vectors are data elements arranged in a row and column vectors are data elements arranged in a column. ...
array = [1 2 3; 4 5 6; 7 8 9] % find() will get the index of element % prints the row and column of the element [row,col] = find(array==5) 输出: [行,列,v] = 查找(X) 如果要查找 3 维数组中存在的所有非零元素的索引,可以使用[row,col,v] = find(X)其中 X 是我们的数组。
array = [1 2 3 4 5 6 2 4 2] % find() will get the index of element % gets the first index of 2 % store it in the index index = find(array==2,1) 1. 2. 3. 4. 5. 6. 7. 8. 输出: 查找(X,n,方向) 您还可以从数组中的两个方向找到元素的索引。通过使用 find(X,n,Dire...
