MATLAB:复制向量'n'次

本文介绍了MATLAB:复制向量'n'次的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个向量，例如

vector = [1 2 3]

我想在自身内复制 n次，即，如果n = 3，则最终结果为:

I would like to duplicate it within itself n times, i.e. if n = 3, it would end up as:

vector = [1 2 3 1 2 3 1 2 3]

对于任何n值，我该如何实现呢?我知道我可以执行以下操作:

How can I achieve this for any value of n? I know I could do the following:

newvector = vector; for i = 1 : n-1 newvector = [newvector vector]; end

这似乎有点麻烦.还有更有效的方法吗?

This seems a little cumbersome though. Any more efficient methods?

推荐答案

尝试

repmat([1 2 3],1,3)

我将让您检查repmat的文档.
