How can i read certain columns from txt file and save them for later usage?

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

Hi, and thank you, but it has a problem with the function load.

i am trying now this way, but it shows me only 0 as results:

fid = fopen('Aerosil_C10_T40_001.txt', 'r');

T = textscan(fid, '%f %*f %f %f %*f %*f %*f %*f %*f %*f %*f','headerLines',3,'delimiter', ' ');

fclose(fid);

data=T{1:3:4}
