数据格式如下：
数据有M行，每行有4列，4列之间用“,”分开，每列中的数据用“%%”分开
提取这些数据并保存
数据文件内容如下：
RawData.xlsx
aaaaa,bbbb%%cccc%%ddddd,eeeee%%ffffff%%gggggg,hhhhhh
jjjjjjjjjjj,kkkkkkkkkk,,
function [stData] = ReadData(varargin)if nargin==0 filename = 'RawData';elseif nargin==1 filename = varargin{1}; else error('Incorrect number of input arguments.') end [NUM,TXT,RAW]=xlsread(filename);stData = struct([]);for i = 1:size(RAW,1)LINE = regexp(RAW{i},',','split');LineData = {}for j = 1:size(LINE,2)COLUME = regexp(LINE{j},'%%','split');ColumeData = {};for k = 1:size(COLUME,2)ColumeData = [ColumeData COLUME{k}];endcolName = strcat('col' , num2str(j));stData(i).(colName) = ColumeData;LineData = [LineData ColumeData];endendsave('DataFile.mat', 'stData');
读取结果如下：
