Hi Halil,
Probably you want to extract the each column separately from the text file.
You can take the help from the below code:
ans = readtable("filename.txt");
a = ans(:, 1);
b = ans(:, 2);
c = ans(:, 3);
% a, b and c will be your required columns
Hope it helps!

No, a b c would end up as tables with one variable each, not as numeric. Use readmatrix() or use {} indexing

Use readtable (use column headers as variable names) or readmatrix (will need to skip the first row) instead.
