如何在MATLAB中的数组中找到最大值及其索引?
问题描述：
假设我有一个数组，a = [2 5 4 7].返回最大值及其索引的函数是什么?
Suppose I have an array, a = [2 5 4 7]. What is the function returning the maximum value and its index?
例如，在我的情况下，该函数应返回7作为最大值，并返回4作为索引.
For example, in my case that function should return 7 as the maximum value and 4 as the index.
答
函数为max.要获得第一个最大值
The function is max. To obtain the first maximum value you should do
[val, idx] = max(a);
val是最大值，而idx是其索引.
val is the maximum value and idx is its index.
