Hi all, I have attached one of the txt I need to extract only the numeric data from, skipping thr headers. it works for that file but I want to extens the code to files with a different (unknown) number of columns. Can anyone help me to modify it?
The piece of code I used is:
fid=fopen('text.txt');
data=textscan(fid,'%f %f %f %f %f %f %f %f %f %f','HeaderLines','4');
data=cell2mat(data);
fclose(fid);
Thanks

This should work for any number of columns and it automatically detects the number of header rows and the variable names.
t = readtable('text.txt')
t = 117×10 table
