如何在Matlab中向不同长度的向量添加重复模式

问题描述

问题

假设我有两个任意长度的向量.让我们叫一个pattern，另一个叫series.现在，我想自动将重复的pattern添加到我的series中.

Suppose I have two vectors of arbitrary length. Lets call one pattern and the other series. Now I want to add my repeated pattern to my series in an automatic way.

通常可以假定pattern比series短，但是如果另一种方法也可行的话，那会很好.在这种情况下，应仅使用pattern的前几个值.

Typically one can assume that pattern is shorter than series, but it would be nice if the alternate way also worked. In this case just the first few values of pattern should be used.

示例

pattern = 1:3;
series = 1:10;

应该给

 2     4     6     5     7     9     8    10    12    11

到目前为止我发现了什么?

我进行了搜索，但没有找到一种实现我想要的优雅方法.

I have searched around but did not find an elegant way to achieve what I want.

• 我找到的最简单的解决方案是使用padarray，但是我没有此可用的
• 我自己认为不优雅的解决方案是使用repmat重复图案足够的次数，然后切割末端.

• The easiest solution I found uses padarray, however I do not have this available
• My own solution,that I don't consider to be elegant, is using repmat to repeat the pattern a sufficient amount of times and then cutting of the end.

推荐答案

您可以使用索引代替repmat:

You could use indexing instead of repmat:

result = series + pattern([mod(0:(numel(series) - 1), numel(pattern)) + 1]);
