There are many.mat file (1.mat; 2.mat; 3.mat...), all these files have many variables, however, all these file contains one variable name 'data' (different values in different file). I hope to change the variable name ('data' ) into '1_data.mat, 2_data.mat, 3_data.mat... 'and save these files into another folder. I appreciate it if someone give me some advice. Thanks in advance.

Something like this
files = dir('*.mat');
folder_path = 'C:\...'; % path to folder where you want to save the new files
for i = 1:numel(files)
old_name = files(i).name;
new_name = strrep(old_name, '.mat', '_data.mat');
new_name = fullfile(folder_path, new_name);
data = load(old_name);
data = data.data;
save(new_name, 'data');
end
