GNU Octave/Matlab：如何获取数组中三个最大值的索引？

Question

Let's say I have an array A = [ 41 13 22 18 32] How can I get the indexes of the three greatest values?

In this example I expect to get 1,5,3 (indexes of 41,32,22).

Thanks!

Answer 1

According to this documentation:

A = [ 41 13 22 18 32];
[val idx]=sort(A,'descend');
top3_idx=idx(1:3)

It works in Octave online
