如何水平连接矩阵? [英] How to concatenate matrices horizontally?

问题描述

我有两个 3 -by- 3 矩阵:

I have two 3-by-3 matrices:

A= [ 1 2 3 
     1 1 1
     0 1 1] 

B= [ 1 2 1 
     1 1 1
     2 2 2]

如何连接A和B矩阵以创建如下所示的concat矩阵?

How do I concatenate the A and B matrices to create the concat matrix as seen below?

concat= [1 2 3 1 2 1
         1 1 1 1 1 1
         0 1 1 2 2 2]

推荐答案

这里有几种可能.最简单，最常见的一种:

There are a few possibilities here. The easiest, and most common one:

concat = [A, B]

以下内容被某些人认为是更可靠的(因为偶然地，可能会执行concat = [A; B]，这会垂直将它们连接起来):

The following is considered more robust by some, (because one might, on accident, do concat = [A; B], which would concatenate them vertically):

concat = horzcat(A, B)
