【代码】Matlab 读写文件

这里以wav文件为例，自动化读取和写入文件代码：

1、循环加载某一格式的数据，例如.wav文件

1、循环加载某一格式的数据，例如.wav文件

folder = pwd;
folder_data = [folder '\ari0_1209\'];
folder_save = [folder '\e0\'];
files = dir([folder_data '/*.mat']);
N = length(files);      % the number of the files

for m= 1:N
    file = [folder_data files(m).name];
    % res.file = file;
    load(file);
end


2、循环存储文件

chr = ['subject',num2str(i),'.mat'];
save(chr,'hl','hr');

格式化与指定文件夹输出
chr = ['subject',num2str(m,'%03d'),'.mat'];
save([folder_save chr],'hl','hr');

3、返回上层文件夹
	% get the father folder
	str = pwd;
	index_dir = strfind(str,'\');
	str_temp = str(1:index_dir(end)-1);
	
4、读子文件夹
	
	folder_data = [str_temp '\standard_hrir_database'];
	subdir = dir( folder_data);    
	
	if( isequal( subdir( index ).name, '.' )||…
	        isequal( subdir( index ).name, '..')||...
	        ~subdir( index ).isdir)               % 如果不是目录则跳过
	        continue;
	    end
	    subject_num = subject_num+1;
	    subdirpath = fullfile( folder_data, subdir( index ).name, '*.mat' );
	
	    mat = dir( subdirpath );
	    datpath = fullfile( folder_data, subdir( index ).name, mat.name);
	    load( datpath );
	

for m= 1:N

    file = [folder_data files(m).name];

    % res.file = file;

    load(file);

end

        ~subdir( index ).isdir)               % 如果不是目录则跳过

        continue;

    end

    subject_num = subject_num+1;

    subdirpath = fullfile( folder_data, subdir( index ).name, '*.mat' );

 

    mat = dir( subdirpath );

    datpath = fullfile( folder_data, subdir( index ).name, mat.name);

    load( datpath );
