在矩阵中查找前n个元素 [英] Find top n elements in matrix

问题描述

我有一个包含值的矩阵，我希望找到n个最小值的索引.

I have a matrix which contains values and I wish to find the index of the top n minimum values.

我使用以下代码来找到最小值的最大值:

I use the following code for finding the minimum most value:

[r,c]=find(Result==min(min(Result)));

我找不到其他问题堆栈溢出，回答了这个问题，请帮忙

I cant find any other questions on stack overflow which answer the question, please help

推荐答案

也许您可以执行以下操作:

Maybe you could do something like this:

sorted = sort(Result(:));
topten = sorted(1:10);
[~,ia,~] = intersect(Result(:),topten(:)); % // Get the indices of the top ten values
[r,c]=ind2sub(size(Result),ia); % // Convert the indices to rows and columns
