寫入特定的細胞在CSV文件

Question

我需要編寫包含像標籤單元陣列：

已啓動：截至：開始：截至：開始：結束：...

到特定的行和和在csv文件列，但是當我使用類似：

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

它在一個單獨的細胞寫入每個字母並覆蓋現有數據（標籤（3）的類型是細胞中的載體）。

任何幫助，將不勝感激。

這是代碼的簡略版：

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是一樣的東西：

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

隨着cell2csv.m，你只需要調用cell2csv('mem.csv', tag)，它會寫入單元格將數組tag轉換成逗號分隔值文本文件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); 
      % Conversion of decimal separator (4 Europe & South America)

      if decimal ~= '.' 
       var = strrep(var, '.', decimal); 
      end 
     end 
     % If logical -> 'true' or 'false' 
     if islogical(var) 
      if var == 1 
       var = 'TRUE'; 
      else 
       var = 'FALSE'; 
      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 
     fprintf(datei, '\n'); 
    end 
end 
% Closing file 
fclose(datei); 
% END
