在 MATLAB Online 中打开

OutputFilePath = 'D:\outputData';
OutputFileName = 'OutSuggestion.csv';
filename = fullfile(OutputFilePath, OutputFileName);
[fid, msg] = fopen(filename, 'wt');
if fid < 0
  error('Could not open file "%s" because "%s"', fid, msg);
end
fprintf(fid, '%s,%s\n', OutputData{1,1}, OutputData{1,2});
temp = OutputData(2:end, :).';      %transpose is important
fprintf(fid, '%s,%f\n', temp{:});
fclose(fid);
