我需要编写一个包含以下标签的单元格数组：

已开始：已结束：已开始：已结束：已开始：已结束：...

到 csv 文件中的特定行和列，但是当我使用类似的东西时：

csvwrite(fName, tag(3), 4,0)

它将每个字母写入一个单独的单元格并覆盖现有数据（tag(3) 是单元格类型的向量）。

任何帮助，将不胜感激。

这是代码的简短版本：

data = importdata('samplelog', ' ');


for i=1:length(data)
    % Extracting the tags 
    [start_i, end_i] = regexp(data{i}, '\D+:');
    tag{i} = data{i}(start_i:end_i);
end

fName = 'mem.csv';
fid = fopen(fName, 'w+');

csvwrite(fName, tag(3), 4, 0);

其中 samplelog 类似于：

START: 2013-05-04 19:13:06.188
ENDED: 2013-05-04 19:22:41.617
START: 2013-05-04 19:25:52.382
ENDED: 2013-05-04 19:35:27.827

使用cell2csv.m，您只需调用cell2csv('mem.csv', tag)，它就会将元胞数组tag写入逗号分隔值文本文件mem.csv中。

单元格2csv.m：

function cell2csv(fileName, cellArray, separator, excelYear, decimal)
% Writes cell array content into a *.csv file.
% 
% CELL2CSV(fileName, cellArray, separator, excelYear, decimal)
%
% fileName     = Name of the file to save. [ i.e. 'text.csv' ]
% cellArray    = Name of the Cell Array where the data is in
% separator    = sign separating the values (default = ';')
% excelYear    = depending on the Excel version, the cells are put into
%                quotes before they are written to the file. The separator
%                is set to semicolon (;)
% decimal      = defines the decimal separator (default = '.')

    decimal = '.';
end

        if excelYear > 2000
            var = ['"' var '"'];
        end
