I have multiple text files and i want to import each of them as separate data (the number of text files is changing) I have taken some help from the previously asked question and written a small code but i am not being able to import any data. I have attached the text file and the code. I will really appreciate any help i this regard.

input_folder = 'T:New\files';
files = dir(fullfile(input_folder, '*.txt'));
file_paths = fullfile({files.folder}, {files.name});
for i = 1 : numel(file_paths)
    format = '%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f';
    data = textscan(file_paths{i}, format,'headerlines', 7);
end

The textscan function requires either an fid as input, or a character array. Your code doesn't actually read the data from the file, but from the file name.

It will also overwrite the variable data every file.

thanks.....working

clear all;
D = 'T:\New\files';
S = dir(fullfile(D, '*.txt'));
N = length(S);
A = cell(N,1);
fmt = '%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f';
% fmt=repmat('%f',1,2);
for k = 1:N
  fid = fopen(fullfile(D,S(k).name), 'r');
  A(k)= textscan(fid, fmt, 'Delimiter', '\t', ...
                           'headerlines', 7, ...
                           'CollectOutput', 1);
  fid=fclose(fid);
end
