Hello,
For example I have different data file named data1.txt, data2.txt, data3.txt... etc. Now I want to read the data from each text file one by one using a loop and save them in a matrix and then plot. I'm out of my depth here.
Any help would be very much appreciated. Thanks..!!

A regular google will give you ton's of sites. This topic is discussed to death in mathworks.
dinfo = dir('*.txt'); % get the text files from folder
for K = 1 : length(dinfo)
thisfilename = dinfo(K).name; %just the name
%load this file
% thisdata = load(thisfilename);
end
plotting, reading the file depends on how your text file is.

If you want to import the files in alphanumeric order than you could download my FEX submission natsortfiles, and use the examples to base your code on:
P = 'C:\Test'; % directory path
S = dir(fullfile(P,'data*.txt'));
S = natsortfiles(S);
for k = 1:numel(S)
F = fullfile(P,S(k).name)
... your code here
end
