如何用MATLAB寫一程式呈現3*3矩陣(matrix)?

Question

A為3*3矩陣(matrix),A=[b1 b2 b3;c1 c2 c3;d1 d2 d3],裏面的元素為b1 b2 b3;c1 c2 c3;d1 d2 d3,而b1 b2 b3;c1 c2 c3;d1 d2 d3各有9個值如下:
b1=1,2,3,4,5,6,7,8,9
b2=1,2,3,4,5,6,7,8,9
b3=1,2,3,4,5,6,7,8,9
c1=1,2,3,4,5,6,7,8,9
c2=1,2,3,4,5,6,7,8,9
c3=1,2,3,4,5,6,7,8,9
d1=1,2,3,4,5,6,7,8,9
d2=1,2,3,4,5,6,7,8,9
d3=1,2,3,4,5,6,7,8,9
請問要如何用MATLAB寫一程式呈現A

Answer 1

先定義 b1, b2, b3, c1, c2, c3, d1, d2, d3, 再定義 A 就可以。
b1=[1,2,3,4,5,6,7,8,9];
b2=[1,2,3,4,5,6,7,8,9];
b3=[1,2,3,4,5,6,7,8,9];
c1=[1,2,3,4,5,6,7,8,9];
c2=[1,2,3,4,5,6,7,8,9];
c3=[1,2,3,4,5,6,7,8,9];
d1=[1,2,3,4,5,6,7,8,9];
d2=[1,2,3,4,5,6,7,8,9];
d3=[1,2,3,4,5,6,7,8,9];
A=[b1 b2 b3; c1 c2 c3; d1 d2 d3]

Answer 2

用cell陣列
A={};
A{1,1}=[1,2,3,4,5,6,7,8,9]
A{1,2}=[1,2,3,4,5,6,7,8,9]
A{1,3}=[1,2,3,4,5,6,7,8,9]
A{2,1}=[1,2,3,4,5,6,7,8,9]
A{2,2}=[1,2,3,4,5,6,7,8,9]
A{2,3}=[1,2,3,4,5,6,7,8,9]
A{3,1}=[1,2,3,4,5,6,7,8,9]
A{3,2}=[1,2,3,4,5,6,7,8,9]
A{3,3}=[1,2,3,4,5,6,7,8,9]

Answer 3

不知道我沒學過耶
去問別人或教授!!
我可不知道ㄛ
不然我也沒別的辦法
