How to load .txt data from different subfolders and store them in a hyper matrix using a for loop, there are 19 subfolders (subfolder 1 ... 19), and each one contains 7 .txt files of my interest with different names that go from (pt1 ... pt7.) Thank you in advance.

You can use the dir function to list all the txt files in the folder and its subfolders.
mytopleveldir = "C:\path\to\my\toplevel\dir";
alltxtfiles = dir(fullfile(mytopleveldir,'**','*.txt'));
pat = {'pt1' 'pt2' 'pt3'}; %etc
filter = startsWith({alltxtfiles.name},pat); %use appropriate filter to get files of interest
alltxtfiles = alltxtfiles(filter);
alldata = cell(length(alltxtfiles),1);
for i = 1:lenght(alltxtfiles)
% use your import function or readtable
alldata{i} = readtable(fullfile(alltxtfiles(i).folder,alltxtfiles(i).name));
end
% concatentate data based on your data structure
alldata = vertcat(alldata{:});
