hello
this is an example that shows how I could read one then multiple text files (and applying a natural name sorting)
you can expand on that
I noticed the data are spread in two sections in your files but the code shows how to retrieve both data sets;
you can build on that , I don't know how you want to further organize the data as you process all the text files;
the natural sorting code is from FEX : Natural-Order Filename Sort - File Exchange - MATLAB Central (mathworks.com)
I attached the two functions for convenience
my code is bellow :
clc
clearvars
%% read one file (example 1)
filename = 'beta_1_kappa_05_cbeta1_1.txt';
[data1,data2] = myreadfunction(filename);
figure(1)
plot(data1)
hold on
plot(data2)
hold off
%% read multiple files (example 2)
fileDir = pwd; % currrent directory
fileNames = dir(fullfile(fileDir,'*.txt')); % get list of files in directory
fileNames_sorted = natsortfiles({fileNames.name}); % sort file names into order (https://fr.mathworks.com/matlabcentral/fileexchange/47434-natural-order-filename-sort)
m = length (fileNames_sorted);
%% main loop for data extraction and concatenation
outdata = [];
figure(2);
for k = 1:m
[data1,data2] = myreadfunction(fullfile(fileDir, fileNames_sorted{k})) ;
plot(data1)
hold on
plot(data2)
% your code here...
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function [data1,data2] = myreadfunction(filename)
a = readlines(filename);
% find / extract the two sets of data - separated by text
start_indexes = find(contains(a,'(('));
stop_indexes = find(strcmp(a,')'));
data1 = str2num(char(a(start_indexes(1)+1:stop_indexes(1)-1)));% first (upper) segment of data
data2 = str2num(char(a(start_indexes(2)+1:stop_indexes(2)-1)));% second (lower) segment of data
end
