要创建每行包含多个元素的数组，请使用逗号“,”或空格分隔各元素。这种类型的数组称为行向量。
disp('Create an array with four elements in a single row:')
disp('>> a = [1 2 3 4]')
a = [1 2 3 4]
Create an array with four elements in a single row:
>> a = [1 2 3 4]
a =
1 2 3 4
要创建每列包含多个元素的数组，请用分号“;”分隔这些元素。这种类型的数组称为列向量。
disp('Create an array with four elements in a single column:')
disp('>> a = [1; 2; 3; 4]')
a = [1; 2; 3; 4]
Create an array with four elements in a single column:
>> a = [1; 2; 3; 4]
a =
1
2
3
4
要创建包含多行的矩阵，请使用分号分隔各行。
disp('Create a matrix with three rows and three columns:')
disp('>> a = [1 2 3; 4 5 6; 7 8 9]')
a = [1 2 3; 4 5 6; 7 8 9]
Create a matrix with three rows and three columns:
>> a = [1 2 3; 4 5 6; 7 8 9]
a =
1 2 3
4 5 6
7 8 9
要创建等间距的数组，请使用“:”运算符指定起点和终点。
disp('Create an array that starts at 1, ends at 9, with each element separated by 2:')
disp('>> x = 1:2:9')
x = 1:2:9
Create an array that starts at 1, ends at 9, with each element separated by 2:
>> x = 1:2:9
x =
1 3 5 7 9
创建矩阵的另一种方法是使用函数，如 ones、zeros 或 rand。
disp('Create a 1-by-5 matrix of 0''s:')
disp('>> z = zeros(1, 5)')
z = zeros(1, 5)
Create a 1-by-5 matrix of 0's:
>> z = zeros(1, 5)
z =
0 0 0 0 0
