How do I load multiple .mat files and save them as variables?

So I'm trying to load multiple .mat files into matlab. In the current folder, my .mat files are named "test1.mat" to "test2036.mat", so 36 test cases in total.

Can I have some help in importing all of the test cases and saving as variables such as "test1Data", "test2Data" etc.

Anyhelp is much appreciated! Thanks :)

"...my .mat files are named "test1.mat" to "test2036.mat", so 36 test cases in total."

From 1 to 2036 gives ... 2036 test cases. Or can multiple files correspond to one test case?

Thanks for your quick response, I made an error in the original question, it shouldn't read test2036.mat but just test36.mat

P = '.'; % absolute or relative path to where the files are saved.
S = dir(fullfile(P,'test*.mat'));
for k = 1:numel(S)
    F = fullfile(P,S(k).name);
    C = struct2cell(load(F));
    S(k).data = C{1}; % assuming exactly one variable per file, which
end                   % is important information you did not tell us.

Your file data will be stored in the structure array S. You can trivially loop over all of S to process the imported data.

For example the second file name and its corresponding data:

S(2).name
S(2).data

You can also use the following convenience syntax to access the field data of S:

If you expect those files to be listed in alphanumeric order, you can download and use this:
