then the new matrix will be 2.7696 2.7696 2.7696 2.7696 2.0950 2.0922 2.0922 2.3108 2.3966 2.3966 2.3966 2.9068 2.0250 2.0250 2.0250 2.0250 how do i do it? and on top of that i would like to know, which row has the max value. 댓글 수: 5 ...
Hello everyone, Suppose there can be the max value at more than one location, how can I catch the first max value. ThemeCopy A = [6;7;21;4;9;21;5;1]; max(A(:)) [maxValue, linearIndexesOfMaxes] = max(A(:)); [rowsOfMaxes colsOfMaxes] = find(A == maxValue) a...

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 the right answer yet. This is a simple example but in my big matrix there might be more than an answer. For example two max ...
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。矩阵a中存在多个最大值，但它们不恰好等于max。计算最大值时出现了舍入误差，导致最大值与预期值略有不同。为了避免这种情况，可以先确定矩阵a的最大值，然后再查找等于...
