Question

我在MATLAB R2012a中有一个单元格数据类型，不同的单元格具有不同的尺寸，我无法在表格或文本文件中显示结果。两者都很棒。我的手机看起来像这样

'detected' 'crane'   crane' 'time'
'overlap'   [99,88] [99,88]  900
'overlap'   [99,98] [99,88]  1000

... 所以问题是起重机包含2个数字的数组。

我希望在表格中查看此内容并将其打印到文本文件中，但我不断收到与错误尺寸有关的错误。

我试过了

T=cell2table(collision(2:end,:),'Variable Names', collision(1,:));

并收到错误

未定义的函数cell2table，用于输入“cell”类型

我还尝试将每个单元格制作成矩阵，例如

crane1data = cell2mat(collision(2:end,2))

然后尝试将它们全部组合，但它们的大小不同1x2和2x2所以我得到错误

CAT参数尺寸不一致

感谢您的帮助！

Answer 1

假设你有这个单元格数组：

>> C = {
    'detected'  'crane1'  'crane2' 'time'
    'overlap'   [99,88]   [99,88]  900
    'overlap'   [99,98]   [99,88]  1000
}
C = 
    'detected'    'crane1'        'crane2'        'time'
    'overlap'     [1x2 double]    [1x2 double]    [ 900]
    'overlap'     [1x2 double]    [1x2 double]    [1000]

如何将其转换为MATLAB表：

>> T = cell2table(C(2:end,:), 'VariableNames',C(1,:))
T = 
    detected      crane1      crane2     time
    _________    ________    ________    ____
    'overlap'    99    88    99    88     900
    'overlap'    99    98    99    88    1000

Answer 2

您可以将所有单元格转换为字符串并使用fprintf：

 C = {
    'detected'  'crane1'  'crane2' 'time'
    'overlap'   [99,88]   [99,88]  900
    'overlap'   [99,98]   [99,88]  1000
};

[nRow nCol] = size(C);
fID = fopen('textFile.txt','w');
for i = 1:nRow
    for j = 1:nCol
        if ~ischar(C{i,j})
            fprintf(fID,'%10s',num2str(C{i,j}));
        else
            fprintf(fID,'%10s',C{i,j});
        end

        if j == nCol
            fprintf(fID,'\n');
        end
    end
end
fclose(fID);

textFile.txt中的结果：

  detected    crane1    crane2      time
   overlap    99  88    99  88       900
   overlap    99  98    99  88      1000

Answer 3

尝试以下方法：

采用问题中发布的相同示例

C = 

    'detected'    'crane1'        'crane2'        'time'
    'overlap'     [1x2 double]    [1x2 double]    [ 900]
    'overlap'     [1x2 double]    [1x2 double]    [1000]

ds=cell2dataset(C); % This command converts the cell array to dataset assuming the first 
                    % row as the header.
export(ds,'file','test.txt'); % This will `export` the `dataset` to the text file 
                              % `test.txt`

这将保存文本文件，结果如下：

detected    crane1_1    crane1_2    crane2_1    crane2_2    time
overlap        99          88          99          88        900
overlap        99          98          99          88       1000

此处crane1_1和crane1_2对应crane1的两个子列。希望这会对你有所帮助。
