Saving Multiple .dat files

I have a matrix with size of 2000*1000. I want to save it into multiple .dat files in such way that each .dat file should have 2000*1 (One vector). So in this way I will have 1000 dat files. I tried many ways but no success yet. Any idea?

This should work

A   = rand(2000,1000);
for col = 1:size(A,2)
    filename = ['Column_',num2str(col),'.dat'];
    writematrix(A(:,col),filename)
end
