Use data in text files and use that data in Matlab

1 view (last 30 days)
Hello good day.
I hope you can help me.
I have a text file called 'Gain' that has 8 columns of data, each column has a header and 181 numeric data.
I just want the numeric data (181) from the third column of the text file and
use them in a Matlab file as matrix 181 X 1
How I do this?
I would be infinitely grateful for your help.
Greetings.

Try
data = importdata(filename);
column3 = data.data(:,3);
Write back if you have problems, and attach your file.
