在Matlab中查找匹配两个条件的向量元素 [英] Find vector elements matching two conditions in Matlab

问题描述

我有一个向量a = [1 5 3 4 2].我想找到 a 的所有元素，它们是 1<a<5.我如何在 Matlab 中做到这一点?

I have a vector a = [1 5 3 4 2]. I'd like to find all elements of a, which are 1<a<5. How do I do it in Matlab?

我个人开发了一种解决方案，但是很麻烦:

Personally I've developed one solution, but it's cumbersome:

a = [1 5 3 4 2];
ix = find(a>1);
ix = ix(find(a(ix)<5));
disp(a(ix))

有什么更好的方法?

推荐答案

使用逻辑索引:

>> a = [1 5 3 4 2];
>> a = a(1 < a & a < 5)
a = 
    3    4    2
