Hi All,

I have large text file which its content is as follows:

A B C D E ...

12.3 14.43 15.67 17.56 23.95 ...

.

this file has 82 columns and something about 10000 lines, And I am going import these data using a script into an array or something, and then plot them (for example B Vs. C). Actually, I think there should be a way to do this, but I don't know how. So, it's so appreceiated if someone could help with this.

thanks.

在 MATLAB Online 中打开

data = importdata(mytextfile) ; 
B = data(:,2) ; 
C = data(:,3) ; 
plot(B,C)

Also read about readtable, load, textscan.
