Reading multiple txt files and placing numerical data in a matrix

Hi all, I'm trying to read multiple file text without the header and pile up their numerical content. I have attached an example txt file.
Here is the basic code I use:
[filename,pathname,d]=uigetfile('*.txt','MultiSelect','on');
filepath=fullpath(pathname,filename);
a=readtable(filepath);
a=table2array(a);
It works for 1 fIle but gives an error for more files selected. And then once I imported correctly multiple files, how do I pile their numerical content? I guess have to insert that in a for cycle. Bear in mind that different files can have different number of columns and rows.
Thanks in advance to anyone who will help me

"but gives an error for more files selected" - whenever you mention an error in the forum, attach a copy of the complete error message instead of letting the readers guess, what you can see already.

a = readtable(filepath);
a = table2array(a);
Should be equivalent to:
a = readmatrix(filepath)

[filename, pathname] = uigetfile('*.txt','MultiSelect','on');
filename = cellstr(filename);
data = [];
for k = 1:numel(filename)
filepath = fullpath(pathname,filename);
tab = readtable(filepath);
data = cat(1, data, table2array(tab));
end

@lacopo: I've copied "fullpath" from your example in the question. Maybe "fullfile" is meant.
