projectdir = '/path/to/files'; %could be '.'
dinfo = dir( fullfile(projectdir, '*.mat'));
filenames = fullfile({dinfo.folder}, {dinfo.name});
nfiles = length(filenames);
frames = cell(nfiles,1);
labels = cell(nfiles,1);

%do not assume that the variable names are the same for each time
for K = 1 : nfiles
    thisfile = filenames{K};
    [~, basename, ~] = fileparts(thisfile);
    filestruct = load(thisfile);
    fields = fieldnames(filestruct);
    frames{K} = filestruct.(fields{1});
    labels{K} = categorical(basename);
end

output = cell2struct([frames,labels], {'frame', 'label'}, 2);

The output will be a (number of files x 1) struct array with fields 'frame' and 'label'

I have attached .mat file please add label in it in categorical form.
