Load multiple files on MATLAB

So I have 10 data files and each data file contains X-cordinate and Y-cordinate of a ball for 100 frames.

The name of my files are like exp1.dat, exp2.dat, exp3.dat and so on till exp10.dat.

All of these files contain 2x100 data.

I have a code that calculates the velocity autocorelation of the ball for 100 time frames using the X and Y-cordinate.

What I want is to know how to write a code so that I can have a loop to load these files in sequence and caluclate the VACF for each of these data files and find mean of all 10 VACF ?

n_files = 10;

VACF_all = zeros(n_files,100); % Pre-allocate a matrix to store all the VACF results.
                               % I assume the VACF you calculate for each file is a 1x100 vector (no idea if that's true)
for ii = 1:n_files
    file_name = sprintf('exp%d.dat',ii);
    % ...
    % load the file, calculate VACF
    % ...
    VACF_all(ii,:) = VACF; % store VACF as the ii-th row of VACF_all
end

mean_VACF = mean(VACF_all, 1); % take the mean of all 10 VACFs
