Question

我需要编写一个包含以下标签的单元格数组：

STARTED：ENDED：STARTED：ENDED：STARTED：ENDED：...

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)

它将每个字母写在一个单独的单元格中并覆盖现有数据（tag（3）是一个单元格类型的向量）。

任何帮助将不胜感激。

这是代码的简要版本：

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);

其中样本日志类似于：

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)，它就会将单元格数组tag写入逗号分隔值文本文件mem.csv。

cell2csv.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 = '.')

%% Checking für optional Variables
if ~exist('separator', 'var')
    separator = ',';
end

if ~exist('excelYear', 'var')
    excelYear = 1997;
end

if ~exist('decimal', 'var')
    decimal = '.';
end

%% Setting separator for newer excelYears
if excelYear > 2000
    separator = ';';
end

%% Write file
datei = fopen(fileName, 'w');

for z=1:size(cellArray, 1)
    for s=1:size(cellArray, 2)

        var = eval(['cellArray{z,s}']);
        % If zero, then empty cell
        if size(var, 1) == 0
            var = '';
        end
        % If numeric -> String
        if isnumeric(var)
            var = num2str(var);

            end
        end
        % If newer version of Excel -> Quotes 4 Strings
        if excelYear > 2000
            var = ['"' var '"'];
        end

        % OUTPUT value
        fprintf(datei, '%s', var);

        % OUTPUT separator
        if s ~= size(cellArray, 2)
            fprintf(datei, separator);
        end
    end
    if z ~= size(cellArray, 1) % prevent a empty line at EOF
        % OUTPUT newline
