I have a=[ 1 2 3; 7 8 9; 4 5 6; 2 1 3]. I want to find max value in the matrix 'a' but i don't want it to consider second row. So I should get 6 as the answer. How to do it? 댓글 수: 0 댓글을 달려면 로그인하십시오. ...
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: gauss = ...

Need to find value in one matrix that corresponds to the max value of each row in another matrix A = [20 1 3; 6 9 5] [max_value max_index] = max(A,[],2) max_index = [1; 1; 2] B = [4 6 11; 10 20 15; 1 5 9] However, ev...

图像配准(Image Registration),是数字图像处理中非常关键的问题之一。配准的本质是 将两个或多个图像进行对齐以便进行比较、分析或融合的过程。图像配准的目标是 找到一个变换矩阵(Transform matrix),将不同图…
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...
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 ...
