matlab编程 csv到mat格式转换程序

imgDataPath = '';
imgDataDir = dir(imgDataPath);             % 遍历所有文件
SonDataPath = '';
for i = 1:length(imgDataDir)
    if(isequal(imgDataDir(i).name,'.')||... % 去除系统自带的两个隐文件夹
       isequal(imgDataDir(i).name,'..')||...
       ~imgDataDir(i).isdir)                % 去除遍历中不是文件夹的
        continue;
    end
    imgDir = dir([imgDataPath imgDataDir(i).name '/*.csv']); 
    for j =1:length(imgDir)                 % 遍历所有文件
        tempString = imgDir(j).name;%获取文件名称
        tempString = tempString(1:7);%去除csv。我这里文件名长度固定
        tempString = strcat(tempString,'mat');
        SonDataPath1 = strcat(SonDataPath,imgDataDir(i).name);
        if ~exist(SonDataPath1) 
            mkdir(SonDataPath1);
        end
        SonDataPath1 = strcat(SonDataPath1,'/');
        SonDataPath1 = strcat(SonDataPath1,tempString);%保存路径
        ReadPath = strcat(imgDataPath,imgDataDir(i).name);
        ReadPath = strcat(ReadPath,'/');
        ReadPath = strcat(ReadPath,imgDir(j).name);
        Data = csvread(ReadPath,1,0);%读取csv
        Datamat = csvtomat(Data);%数据转换
        
        save(SonDataPath1,'Datamat');       
    end
end
