Hi everyone
I have 20 excel files in a folder, I want to read those files, apply hampel filter and save them into a folder with same names.
files=dir('E:\EEG_RECORDING\Male_Data\*.csv');
files=files(~[files.isdir]);
n=length(files);
for i=1:n
data=xlsread(fullfile(files(i).folder, files(i).name));

Making a file name within a loop is usually accomplished by concatonating a string. I will provide an example, but you will have to change it to come up with your specific desired output.
y = [files(i).folder,'\output_',num2str(i),'.csv'];
