length_of_data = 800; % length of your data
random_data_vector = rand(1,800); % dummy/test data --> update from your file
 
number_of_files = 200; % number of datasets 
 
% preallocate memory to save. Size = 200 x 800
save_data_mat = NaN(number_of_files,length_of_data);
 
% loop over your datasets
for iter = 1 : number_of_files
    
    % for each data set, save the vector of data 
    save_data_mat(iter,:) = random_data_vector;
end
 
disp(size(save_data_mat))

ok what to do if the loop doesn't return 800 exactly? sometimes 850 and sometimes 750
