How to Open all of .mat file in one folder?

Hello, I have some .mat files in a folder, I want to import them all to matlab. I tried to double click each file, however by clicking each file I could only import a variable called : 'ModulatedPulse' . Each time I click another file it will just import another ModulatedPulse and overwrite the origional one.

Why do I keep having this ModulatedPulse variable? What should I do to import all of .mat files at the same time? The names for these files are numbers, for example: "36.mat".

Thank you.

"Why do I keep having this ModulatedPulse variable?"

Because that is what your MAT files contain. What do you expect them to contain?

P = 'absolute or relative path to the folder where the files are saved';
S = dir(fullfile(P,'*.mat'));
for k = 1:numel(S)
    F = fullfile(P,S(k).name);
    T = load(F);
    S(k).ModP = T.ModulatedPulse;
end

The file data are in the structure S which you can access easily using indexing. For example the 2nd file:

S(2).name % filename
S(2).ModP % imported file data
