How can I write self-invoking code for hundreds of wav files for the same loop and call those files to matlab?

How can I write self-invoking code for hundreds of wav files for the same loop and call those files to matlab?I have hundreds of wav files, how can I name them in the loop that I will call them?

It sounds like you just need a simple loop, but what exactly you want to do is unclear to me.

Perhaps you need the dir function to generate the list of file names?

"how can I name them in the loop" - if you mention, how the names should look like, suggesting some code is much easier. What does "self-invoking code" means?

hello

something like this ?

this demoes the excellent FEX submission

Natural-Order Filename Sort - File Exchange - MATLAB Central (mathworks.com)

dir is not 100% sure for natural sorting

in the for loop we show how you can use the created structure S to store new information / code results

expand as you wish

fileDir = pwd; % current directory (or specify which one is the working directory)

S = dir(fullfile(fileDir,'*.wav')); % get list of data files in directory
S = natsortfiles(S); % sort file names into natural order , see : 
           %(https://fr.mathworks.com/matlabcentral/fileexchange/47434-natural-order-filename-sort)


for k = 1:length(S)
    filename = S(k).name % to actually show filenames are sorted (see command window)
    [signal,Fs] = audioread( fullfile(fileDir, filename)); 
 
    % code example below 
    % save signal data inside structure S
	S(k).Fs = Fs; 
	S(k).signal = signal; 
	

end
