Question

我有，D是不匹配的字符串数组

的单元格数组

A = 

{'abc'; 

'acd' ;

'aaa'}


B = 

{'baa' ;

'bbb'}


C = 

{'acc';

'aaa';

'aad'}

D = { {A}, {B}, {C}}

A，B和C的大小不同，我首先不知道它们的大小，所以我将它们组合成D.如何将D转换为单个单元格数组，以便我可以将它们写入excel表？

即。

D = 
{'abc' 'baa' 'acc';

'acd' 'bbb' 'aaa';

'aaa' ' '   'aad'}

Answer 1

您可以让MATLAB在需要时扩展单元阵列：

F={}; 
for k = 1:numel(D), 
    F(1:numel(D{k}), end+1)=D{k}; 
end

导致

F = 
    'abc'    'baa'    'acc'
    'acd'    'bbb'    'aaa'
    'aaa'       []    'aad'

如果将空矩阵作为空字符串很重要，请使用

>> F(cellfun('isempty', F))={''}
F = 
    'abc'    'baa'    'acc'
    'acd'    'bbb'    'aaa'
    'aaa'    ''       'aad'

Answer 2

这将是一种矢量化方法 -

D = { {A}, {B}, {C}} %// Code from question (not tinkering with it)

%// Extract all cells data at each cell index position. 
%// In other words, reduce level of cell data storage by one step.
D1 = vertcat(D{:})

%// Get lengths of each cell
lens = cellfun('length',D1)

%// Initialize output cell array
out_cell = cell(max(lens),numel(lens))

%// Mask of valid cell positions in the output
mask = bsxfun(@le,[1:max(lens)]',lens(:).')

%// Store concatenated cell data into masked positions in output
out_cell(mask) = vertcat(D1{:})

示例运行 -

>> A,B,C
A = 
    'abc'
    'acd'
    'aaa'
B = 
    'baa'
    'bbb'
C = 
    'acc'
    'aaa'
    'aad'
>> out_cell
out_cell = 
    'abc'    'baa'    'acc'
    'acd'    'bbb'    'aaa'
    'aaa'       []    'aad'

请注意，如果您在开始时这样做，则可以完全避免创建D -

D1 = {A,B,C}
