如何添加不同长度的向量? [英] How to add vectors with different length?

问题描述

我想在Matlab或Octave中添加两个具有不同长度的向量.例如

I would like to add two vectors with different lengths in Matlab or Octave. E.g.

aa = [1 2 3 4];
bb = [100 100];

哪个应导致矢量cc包含

Which should result in a vector cc containing

cc = [101 102 3 4]

任何人都可以弄清楚该怎么做吗?

Can anyone figure out how to do this?

更新:这是我最终获得的信号代码，随后我将其转换为灰度图像.

Update: This is the code I ended up with for the signals that I then later convert to grey scale images.

load train;
t = y;
load chirp;
c = y;

tc = c + [t; zeros(length(c) - length(t),1)];

plot(1:length(tc),tc)

非常感谢大家=)

推荐答案

从数学上讲这没有任何意义，但是如果您坚持，可以这样做:

This doesn't make any sense mathematically, but if you insist, you can do this:

cc = aa + [bb zeros(1,2)];
