将结构体数组的字段提取到新数组 [英] Extract field of struct array to new array

问题描述

我有一个结构体，它有 2 个字段:time 和 pose.我在一个数组中组合了这个结构的多个实例，所以一个例子是:

I have a struct, which has 2 fields: time and pose. I have multiple instances of this struct composed in an array, so an example of this is:

poses(1)
    -time = 1
    -pose = (doesn't Matter)
poses(2)
    -time = 2
    -pose = (doesn't Matter)
poses(3)
    -time = 3
    -pose = (doesn't Matter)
...

现在当我打印这个时:

 poses.time

我明白了:

ans =
      1
ans =
      2
ans =
      3

如何获取该输出并将其放入向量中?

How can I take that output and put it into a vector?

推荐答案

使用方括号:

timevec=[poses.time];

棘手的 matlab，我知道我知道，如果你使用结构体，你只需要记住这个 ;)

tricky matlab, I know I know, you'll just have to remember this one if you're working with structs ;)
