MatLab中的[A，B]和[A; B]有什么区别？

Question

% CAT(2,A,B) is the same as [A,B]. 
% CAT(1,A,B) is the same as [A;B]. 

似乎我需要知道这个以了解cat是做什么的。

Answer 1

[A,B] 

是通过将B到A的右侧形成的基质，而

[A;B] 

是通过将乙下面A.

形成的基质也了解horzcat和vertcat。

Answer 2

[A, B] does col cat 
[A; B] does row cat 

如：

x = [1, 2, 3]; 
y = [7, 8, 9]; 

[x, y] == > [1, 2, 3, 7, 8, 9] 

becomes a 1x6 array 




[x; y] == > [1, 2, 3] 
      [7, 8, 9] 

becomes a 2x3 array 

只是尝试在Matlab和开放ANS看到这么MATLAB中的每个操作员可被视为矩阵操作的差异
