如何扩展我的单元格而不会丢失信息

Question

我有一个容纳4个向量的单元格,我想扩展它以便它可以容纳另一个向量.提前致谢.

a = cell(4, 1);
a{1} = [1, 2, 3];
a{2} = [1, 4, 9];
a{3} = [1, 4, 9];
a{4} = [1; 5];

我想添加一个新的矢量[2,7],这样我就可以得到它

a{1} = [2, 7];
a{2} = [1, 2, 3];
a{3} = [1, 4, 9];
a{4} = [1, 4, 9];
a{5} = [1; 5]; 

我怎么能这样做？

Answer 1

a = cell(4, 1);
a{1} = [1, 2, 3];
a{2} = [1, 4, 9];
a{3} = [1, 4, 9];
a{4} = [1; 5];

a = [[2, 7];a]

产量:

a = 

    [1x2 double]
    [1x3 double]
    [1x3 double]
    [1x3 double]
    [2x1 double]
