Read specific column from dat file

Hi..

I am trying to read a specific colum from dat file however, the output is 1*2 cell array..

I would like the output to be [2;4;5;7;9].. I attached the file and the code as well

clearvars; 
clc;
close all; 
fid = fopen('trial_1.dat')
data = textscan(fid, '%d %d[^\n]')
fid = fclose(fid);
% I would like data=[2;4;5;7;9]

Any help please ...

Thanks,

I have been trying but not possible.. I do not understand why ?

[Mathieu NOE]

maybe that extension is not supported by this forum, change it to csv or txt and retry

Simpler:

T = readtable('trial_1.dat.txt')

T = 5×2 table
    sig    olx
    ___    ___

     1      2 
     2      4 
     3      5 
     4      7 
     5      9 

T.olx

ans = 5×1

2 4 5 7 9

No need to use textscan. Just use readmatrix:

f = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/676208/trial_1.dat.txt';
M = readmatrix(f)

M = 5×2

1 2 2 4 3 5 4 7 5 9

M(:,2)

ans = 5×1

2 4 5 7 9
