MatLab中的[A，B]和[A; B]有什麼區別？

Question

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

似乎我需要知道這個以瞭解cat是做什麼的。

Answer 1

[A,B] 

是通過將B到A的右側形成的基質，而

[A;B] 

是通過將乙下面A.

形成的基質也瞭解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 

只是嘗試在Matlab和開放ANS看到這麼MATLAB中的每個操作員可被視爲矩陣操作的差異
