I have a matrix with 5 columns and one million rows. How can I find the max value of every 60 rows in that rows of million 댓글 수: 0 댓글을 달려면 로그인하십시오. 채택된 답변 Jan2014년 10월 12일 ...
Now, there is reason why I don't want to use a max() or similar built-in function to find the maximum value of a matrix. My question is following: Imagine, we have a matrix, let's call it 'gauss' and looks like this: 테마복사 gauss = 0 0.2000 0 0.5000 1.0000 0.6000 0...
thank you! , how can i index each value with its row and coumn index ? Janon 7 Jun 2022 Open in MATLAB Online index = sub2ind(size(inputmatrix), col_idx.', 1:5); inputmatrix(index)% same values as row_max Sign in to comment. ...
>>[m n] = find(a==b);这里[m n]返回的是满足条件的元素的行索引和列索引。如果矩阵a中没有元素等于max，find函数将返回一个空矩阵，如Empty matrix: 0-by-1。如果find函数返回Empty matrix: 0-by-1，则表示矩阵a中不存在与max相等的元素。这可能是由于以下几种原因：矩阵a中没有最大值。
