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. 이 질문에
I Have a code that gives me some output in my command window as a 9 by 80 matrix. I want that when I run the program and it gives me output in the command window, the max and min value should stand outin some way in each column so that I don't have to find them by looking...
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。
cfaImage = max(0,cfaImage); 缩放像素值 RAW 文件元数据通常将白电平表示为数据类型允许的最大值。如果此白电平值远高于图像中的最高强度值,则使用此白电平值进行缩放会导致图像比应有的亮度要暗。为避免这种情况,请使用图像中找到的最大像素值缩放 CFA 图像。 cfaImage = double(cfaImage); maxValue = max...
