Using for loop to load multiple mat files of same names

Hi everyone,

can amyone please help on the following :

I have a folder contains mualiple matfiles C1,C2,C3,C4.....C20.

1- I want to load all these files using for loop . All the files has the same matrix name (data) .. Then i want to claculate the absolute FFT for every single subject as follow:

Y= abs(fft(data));

2- i want to save the result of file 1 with Y1, and file 2 with Y2 and so on till C20 named with Y20.

is there any way I can do it?

Any help will be highly apperciated .

Dear Mr. Kalyan,

i have tried this code but it does not work for me .

path_directory='folder_name'; % 'Folder name'

original_files=dir([path_directory '/*.mat']);

for k=1:length(original_files)

filename=[path_directory '/' original_files(k).name];

image_orginal=imread(filename);

end

Try something like this:

N = 20;
D = 'path to the folder where the files are saved';
for k = 1:N
    F = fullfile(D,sprintf('C%d.mat',k));
    S = load(F);
    Y = abs(fft(S.data));
    F = fullfile(D,sprintf('Y%d.mat',k));
    save(F,'Y')
end
