arrays - Matlab how to create n arrays of equal size matrices from an array of different size matrices

Question

I have an array of different size matrices.I would like to create n arrays each including equal size matrices. So if I have:

 ArrayA =
 <9x10 double>
 <7x10 double>
 <9x10 double>
 <9x10 double>
 <7x10 double>

I would like to obtain:

ArrayA1 =
<9x10 double>
<9x10 double>
<9x10 double>

ArrayA2 =    
<7x10 double>
<7x10 double>

Answer 1

mat = 

[4x5 double]
[4x5 double]
[5x5 double]
[4x5 double]
[5x5 double]
[6x5 double]
[5x5 double]

我假设 all are nx5，因此只检查行。

arr_sizes =  arrayfun(@(x) size(mat{x},1),1:size(mat,1))'

这给出了：

arr_sizes =

 4
 4
 5
 4
 5
 6
 5

现在：

[~, ~, idx] = unique(arr_sizes);

最终输出将是：

tot_arr = arrayfun(@(x) mat(idx == x), 1:max(idx),'UniformOutput',false)';

tot_arr =

{3x1 cell}
{3x1 cell}
{1x1 cell}

现在，tot_arr包含 3 个数组，您调用的数组ArrayA1, ArrayA2等。

tot_arr{1}

ans = 

[4x5 double]
[4x5 double]
[4x5 double]
