Hi, I would know if someone can help me with this. In the file I have, I only need to read the third term of the second column, I mean, the total_z colum, which in the first row is -9.471316e-01. So I need to obtain this term of all the file.
Thanks

I do not have the ability to look at your data. Would you describe the file layout as a numeric data sheet? If so, the simplest way to accomplish what you are asking for is to read the entire file into a matrix, and then extract that one value by indexing.

Hello,
Here is a solution that you can refer:
clear
format long
a = readtable('force1.dat','HeaderLines',4);
b = a(:,4);
c = b{:,1};
n = length(c);
d = zeros(n,1);
for i = 1:n
d(i) = str2double(c{i}(1:end-1));
end
d(1)
Your data is now saved in varibale d.
Best rergards,
Trung
