A=[5 4 1 6;2 1 8 9;2 6 7 7];[m,i]=max(A); % 求各列最大值 M=repmat(m,size(A,1),1); % 按行复制最大值和原矩阵同维数 A(A<M)=0 % 置各列比最大值小的数为零 a =[5 4 1 62 1 8 92 6 7 7];[maxv,index] = max(a);b=zeros(size(a))...
matlab 中[~, index] = max()是什么意思~表示最大值，index表示最大值的位置 如[m,n]=max([1,...
matlab 中~表示最大值，index表示最大值的位置。操作方法如下：1、首先打开matlab软件。在matlab中~=是不等于的意思，主要用于判断两侧表达式是否不相等，如果两个值比较，是不等于的，那么返回结果为真，是等于的，那么返回结果为假。2、下面来使用一下~=，命令行窗口输入1~=2，如下图所示。3、按...

找到这个矩阵中每列的最大值和它在这列中的行数。返回的y是每列的最大值，index是最大值对应的下标（行数）例如 y=magic(3)y = 8 1 6 3 5 7 4 9 2 >> [y,index]=max(y)y = 8 9 7 index = 1 3 2 [y index]=max(y) ，中括号里...
Open in MATLAB Online I'm looking for a way to split my data into group then find the maximum and index of each group. So, I have this code which gives me the maximums but the indexes are not correct. Any idea please. I have asked this question and haven’t got ...
Open in MATLAB Online Loop through the elements of your cell vector a, use the max function to find the maximum value for a, and the second output of max to find which index in index you need to keep. Using the strategy by Jan (with a minor edit): ThemeCopy a = [1 2 5 NaN ...
