How to return number of directory to label objects in a loop

I would like to run a loop where I open a folder, load a matlab file, and label it with a number that increases with each folder I open (ie matlab file from first folder is 1, from second folder is 2 ect). I am using the following command to open each folder and load the matlab file. How do I return the column number from D so that I can label the object with the no. of directory I've opened?

D = dir('Index*')

for k = 1:length(D)

currD = D(k).name

cd(currD)

load 'Summary.mat' summary

# Now I want to label the number of the directory I've opened as = summary

cd ..

Hi @Sarah Bowling,

If you want to label each loaded summary variable with the number of the directory you've opened, you can simply add a new field or variable to your summary struct or variable after you load it.

Here’s how you can do it:

D = dir('Index*'); 
for k = 1:length(D) 
    currD = D(k).name; 
    cd(currD) 
    load('Summary.mat', 'summary') 
    summary.dir_number = k;   % Add a field with the directory number 
    % Now you can save or process summary as needed 
    cd .. 
end 

With this modification, “summary.dir_number” will contain the index of the directory.
