matlab - 找到具有最低最大值的行/列

Question

考虑下面的矩阵:

A = randi([0 100], 5, 7)

---

62   59   20   42   49   41   83
37   34   13   65   82   47   24
93   33   19   93   30   37   20
42   49   74   96   26   41   21
14   85   14   90   77    4   96

first I want to find the maxima of each row and the column index:

   83    7
   82    5
   93    1
   96    4
   96    7

then I need to find the row with the lowest maxima:

82 5 2

so far, I have implemented this:

close all;
clear all;
clc;

A = randi([0 100], 5, 7);

[M1, I1] = max(A, [], 2);

[M1, I1]

[M2, I2] = min(M1);

[M2, I1(I2), I2]

虽然这感觉像是一种解决方法，但我想知道是否有更规范的方法来做到这一点？也许是用于此特定目的的内置函数或 min/max 语法？

P.S. 也在 MATLAB Discord channel 上分享了这个问题.

Answer 1

find 怎么样？

M = min(max(A,[],2));
[i,j] = find(A == M);
[M,j,i]
