如何在Matlab中消除向量中的复数 [英] how to eliminate complex number in a vector in Matlab

问题描述

在Matlab中，假设有一个向量，其元素可以是复杂的或真实的.我想知道如何删除非真实元素，从而减小向量的大小?谢谢和问候！

In Matlab, suppose there is a vector whose elements can be complex or real. I was wondering how to remove the nonreal elements, and consequently reduce the size of the vector? Thanks and regards!

推荐答案

使用 REAL 和 IMAG 函数:

>> x = [1+i; 4+3i; 5+6i]

x =

                          1 +                     1i
                          4 +                     3i
                          5 +                     6i

>> real(x)

ans =

     1
     4
     5

>> imag(x)

ans =

     1
     3
     6
