Reading .txt. data in Matlab

Question

I have a very basic table

Alcohol  Tobacco
6.47    4.03
6.13    3.76
6.19    3.77
4.89    3.34
5.63    3.47
4.52    2.92
5.89    3.20
4.79    2.71
5.27    3.53
6.08    4.51
4.02    4.56

I have tried reading it in using textscan but get blank.

fileID = fopen('TabaccoAlcohol.txt');
C_text = textscan(fileID,'%n',2);

It would be nice in the program using the headings as objects, e.g. Alcohol would be all 11 rows of data. I know Matlab can do this but I can't make it work. Please help.

Use readtable:

>> t = readtable('data.txt')

t = 

    Alcohol    Tobacco
    _______    _______

    6.47       4.03   
    6.13       3.76   
    6.19       3.77   
    4.89       3.34   
    5.63       3.47   
    4.52       2.92   
    5.89        3.2   
    4.79       2.71   
    5.27       3.53   
    6.08       4.51   
    4.02       4.56  

>> t.Alcohol

ans =

    6.4700
    6.1300
    6.1900
    4.8900
    5.6300
    4.5200
    5.8900
    4.7900
    5.2700
    6.0800
    4.0200

You can change your code with this code is given below

It is still empty. The columns are seperated by tab, does that make a difference? – Orongo May 16 '16 at 12:11
Ok. I've cheated. I have manually removed the tab and made a space instead so now it works. – Orongo May 16 '16 at 12:16
This works fine for me. The another method is "load" command. Just use this command: load TabaccoAlcohol.txt – Efecan Kocuklu May 16 '16 at 12:23
