I tried to upload one of the files, but the website site refused as they don't support Dat files. I got a set of dat files and they were generated from another Matlab function. each file contains 4 columns (X,Y,U,V)

You can zip the dat file(s) and upload the zip file.

I used the below command and it read the dat files as a table (1x1500 cell) and each cell include (65536x4 table)

for k = 1:1500

myfilename = sprintf('Vec%05d.dat', k);

mydata{k} = readtable(myfilename);

end

then I tried to convert the table to matrix, but it doesn't work, could you please correct it to me?

for k = 1:1500

mydata1(:,:,k)= table2array(mydata{:,k})

end

P = 'absolute or relative path to where the files are saved';
N = 1500;
C = cell(1,N);
for k = 1:N
    F = sprintf('Vec%05d.dat',k);
    C{k} = readmatrix(fullfile(P,F));
end
A = cat(3,C{:});
