%1维数组
a1_1=[1,2,3,4]
a1_2=[1 2 3 4]
%2维数组a2[][]
a_n=[1 2 3 4;5 6 7 8]
%多维数组，对a2x4数组进行扩展
a_n(:,:,2)=[9 10 11 12;13 14 15 16]
a_n(:,:,3)=[17 18 19 20; 21 22 23 24]%用与其他数据相同的函数进行创建
b = ones(4,4,2) 
c = randn(2,2,3) %获取维数
a1_1_dims=ndims(a1_1)
b_dims=ndims(b)
c_dims=ndims(c)%数组大小
a1_1_size=size(a1_1)
b_size=size(b)
c_size=size(c)
