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.

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
