Apply code on matlab files in different directories ?

I want to apply the code on the .m files present in sub directories. The names of sub-directories started from 001 up to 365 in sequence. Could someone help me to write some code ? I have a very basic knowledge of Matlab scripts.

Thanks in advance!

From Documentation:

path(path,'newpath') adds the newpath folder to the end of the search path. If newpath is already on the search path, then path(path,'newpath') moves newpath to the end of the search path.

In your case, you should do something like this:

your_path = path where you have your sub-directories;
for k=1:365                         % sub-directories started from 001 up to 365 in sequence
    str = strcat(your_path,'\000);  % add the temporary 000 ending 
    file_number = num2str(k);       % convert index to string
    L = length(str);                % length of your path
    LK = length(file_number);       % length of index as string
    new_path = strcat(str(1:L-LK),file_number);   % full new path od kth folder
    path(path,new_path)             % add the kth folder to matlab path
end

First, i would like to appreciate your quick response. I have uploaded the picture and trouble with script. Please provide a solution for the trouble.Your kind help would be highly appreciated !

[Azzi Abdelmalek]

geoabidali, to show your code, just copy and paste it.

[Walter Roberson]

your_path = path where you have your sub-directories;
for k = 1 : 365
  new_path = fullfile(your_path, sprintf('%03d', k));
  addpath(new_path);
end

see the attached tst.m please http://www.mathworks.com/matlabcentral/answers/uploaded_files/35847/tst.m

Why do you go through all that calculation trouble but not record the results for each directory, either by using a cell array or by writing it to a file?

For example

energy{K} = sum(psdest);

at the end of the loop would at least allow the calculated energy to be saved in a variable for use after the loop.

[geoabidali]

i need each variable information that's why i put this energy. I dont have idea how this script could better and meaningful. please help if you can

[Walter Roberson]

The problem is not in the calculation, the problem is that after you calculate the values you do not do anything with them, so the next file replaces the values.

Do you want values saved to a file? If so then which variables do you want saved, and do you want them saved to one file for every input file or do you want all the results combined into one output file?

[geoabidali]

Mr. Walter Roberson i want to save these variables from the code :f, res, AmpTab, FreTab, Amplitudes, Frequencies,psdest, and energy for each file. I want to save one file for input. Thanks a lot for your consideration !

You seem to be working with 365 different subdirectories, but I cannot tell which file or files you want to use out of each subdirectory. Is there a data_hr.mat file in each subdirectory that has a single variable in it? Is there a data_hr.csv file in each subdirectory? Is data_hr the name of a column in a .xls file that has a consistent name in each subdirectory? Is there a data_hr.m file in each subdirectory that is a function that returns data? Are there multiple files in each sub-directory that each need to be processed?

[geoabidali]

I have the files like A00100ADO_E.mat, A00100ADO_N.mat in all the sub-directories and all of them have single variable which is 'data_hr' in each file.
