hello, i would like to ask for some help, because i am in the beginning of learning matlab. So i have a txt file with 11 columns but i only need 3 of them without the headers (1,3 and 4). How can i make it read only them and save them in an array for using them later in the script.
i will upload the file and would appreciate any suggestions! Thank you

data_file=load('Aerosil_C10_T40_001.txt');
j=[1,3,4]; %define column number
colm_dada=data_file(:,j); % Column data for further use
Save colm_data
writetable(colm_data, 'file_name1.txt');
Now you can acess the file_name1.txt file in future work
