Loops in sub folders

I have 10 folders and each one has subfolder which has the same name of all 10 called test. under test folders have subfolders named test1 including the data want to plot two rows.

Okay. What is your question? I'm not really able to follow your explanations. Do you have 100 subfolders, which contain folders, which contain the actually wanted files?

The Question:

Hello star, how can I do his command in loop under different folders in different directories.

if true
data = load(strcat('C.....', filePaths(i,:) ,LPCC.dat'));  end

[Star Strider]

My response:

See: Process a Sequence of Files (link), and How can I process a sequence of files? (link).

10 folders each one has folder named test. Every test folder has folder named test1 including the data.

@Najiya Omar: What exactly is your question?

[Jan]

Since Matlab R2016b the dir command accepts the '/**/' key to search recursively in subfolders.

I got lost, My question is, I want to generate this order for different folders from 1 to 10, each folder has different subfolders, one of them including my file data, which is (LPCC.mat). so in total I have 10 files of (LPCC.dat), then plot two rows represent x,y for these data in one figure x,y

this the order to skip lines
  fidi = fopen('LPCC.dat', 'rt');
D = textscan(fidi, repmat('%f', 1, 13), 'HeaderLines',2, 'CollectOutput',1);

This the loop

myPaths = ['100H' ; '200H' ; '300H' ; '400H' ; '%700H' ; '800H' ; '900H' ; '10000H'];
figure;
hold on;

for i = 1:length(myPaths)
  
  mydata = load(strcat('....', myPaths(i,:) ,'LPCC.dat'));
  
  plot(mydata(:,1),mydata(:,2)));
  
end

And my demo below didn't work??? Please show how you adapted it.

[Najiya Omar]

I can't adapt it with my objectivs

[Image Analyst]

Why not??? Just make the obvious changes. Just change the starting path to be whatever top level folder you want, and change the file pattern from . or *.m to *.dat or whatever you want and it should work fine.

[Najiya Omar]

I got totalNumberOfFiles=0 is that correct!!

I can't debug your adaptation of my code. I have neither the Crystal Ball Toolbox, nor the Mind Reading Toolbox. The only known beta version is only in the hands of Walter Roberson. Until I get a copy, or he answers you, you'll have to post your m-file for us mere mortals.

Thanks

This will not work because it pads the char matrix with spaces:

myPaths = ['100H' ; '200H' ; '300H' ; '400H' ; '%700H' ; '800H' ; '900H' ; '10000H'];

Use a cell string instead:

myPaths = {'100H' ; '200H' ; '300H' ; '400H' ; '%700H' ; '800H' ; '900H' ; '10000H'};

and replace myPaths(i,:) by myPaths{i}.

See attached demos to recursively find files in folders and subfolders.
