MatLab 如何循环从一个文件移动到另一个文件？

发布于 2024-12-11 05:15:54 字数 754 浏览 0 评论 0原文

有没有一种方法可以简单地加载目录中第一个文件的名称而不指定其名称，然后在每次迭代中移至目录中的下一个文件？

我遇到的问题是文件名以 1、1.5、2、2.5、3、3.5 结尾等命名...因此迭代中的 num2str(X) 无助于找到文件。

我试图使用 strrep(s1,s2,s3) 重命名它们，但我再次遇到将它们加载到循环中的相同问题！

我知道我应该一开始就给它们命名，但这些文件太大了，无法再次运行模拟。

这就是我必须重命名文件的内容：

%%%RENAMING A FILE%%%

%Search directory to get number of files
 d1=dir('\MATLAB\Data\NumberedQwQoRuns');
 numfiles = length(d1)-2;


for a=1:numfiles
%Search subdirectory if necessary for count of those folders
d2=dir('\MATLAB\Data\NumberedQwQoRuns\Run'num2str(a));
subdir = length(d2)-2;
for b= 1:subdir

origname= PROBLEM???

Newname=['Zdata' num2str(b) '.txt']
Newfile= strrep(origname, origname, newname)
movefile(origname,Newfile)

end
end

非常感谢您的帮助，阿比德A

Is there a way to simply load the name of the first file in a directory without specifying its name, and then in each iteration move on to the next file in the directory?

I have the problem of the file names being named with 1, 1.5, 2,2.5,3, 3.5 endings etc... so num2str(X) in an iteration will not help to locate the file.

I am trying to rename them using strrep(s1,s2,s3), but yet again I run into the same problem of loading them into a loop!

I understand that I should have named them with more planning at first, but these files are much too large to run the simulations again.

This is what I have to rename the files:

%%%RENAMING A FILE%%%

%Search directory to get number of files
 d1=dir('\MATLAB\Data\NumberedQwQoRuns');
 numfiles = length(d1)-2;


for a=1:numfiles
%Search subdirectory if necessary for count of those folders
d2=dir('\MATLAB\Data\NumberedQwQoRuns\Run'num2str(a));
subdir = length(d2)-2;
for b= 1:subdir

origname= PROBLEM???

Newname=['Zdata' num2str(b) '.txt']
Newfile= strrep(origname, origname, newname)
movefile(origname,Newfile)

end
end

Thank You Very Much for your help,

这是我的解决方案：

%# get runs subdirectories
BASE_DIR = '/path/to/Runs';
runsDir = dir( fullfile(BASE_DIR,'Runs') );
runsDir = {runsDir([runsDir.isdir]).name};           %# keep only directory names
runsDir = runsDir( ~ismember(runsDir, {'.' '..'}) ); %# ignore "." and ".."

for r=1:numel(runsDir)
    %# get files in subdirectory
    runFiles = dir(fullfile(BASE_DIR,'Runs',runsDir{r},'*.txt')); %# *.txt files
    runFiles = {runFiles.name};                                   %# file names

    %# map filenames: 1,1.5,2,2.5,... into 1,2,3,4,...
    [~,ord] = sort(str2double( regexprep(runFiles,'\.txt
我在以下文件结构上测试了它：
Runs/
|
|__Run1/
|  |__1.txt        will become: Zdata_1.txt
|  |__1.5.txt                   Zdata_2.txt
|  |__2.txt                     Zdata_3.txt
|  |__2.5.txt                   etc...
|  |__3.txt
|  |__3.5.txt
|
|__Run2/
   |__1.txt
   |__1.5.txt
   |__2.txt
   |__2.5.txt
   |__3.txt
   |__3.5.txt

,'') ));
    newrunFiles = cellstr( num2str(ord(:),'Zdata_%d.txt') );
    newrunFiles = strtrim(newrunFiles);

    %# rename files
    for f=1:numel(runFiles)
        fname = fullfile(BASE_DIR,'Runs',runsDir{r},runFiles{f});
        fnameNew = fullfile(BASE_DIR,'Runs',runsDir{r},newrunFiles{f});
        movefile(fname,fnameNew);
    end
end

    %# map filenames: 1,1.5,2,2.5,... into 1,2,3,4,...
    [~,ord] = sort(str2double( regexprep(runFiles,'\.txt
I tested it on the following file structure:

    newrunFiles = cellstr( num2str(ord(:),'Zdata_%d.txt') );
    newrunFiles = strtrim(newrunFiles);

    %# rename files
    for f=1:numel(runFiles)
        fname = fullfile(BASE_DIR,'Runs',runsDir{r},runFiles{f});
        fnameNew = fullfile(BASE_DIR,'Runs',runsDir{r},newrunFiles{f});
        movefile(fname,fnameNew);
    end
end

I tested it on the following file structure:
