use dlmread:

rng = [7 2 10 4]; % get lines 7-10 (fields 2-4) and store in a matrix
dlmtr = ' '; % use this is space is your delimiter
M = dlmread('filename.txt', dlmtr, rng);

% now your data is stored in matrix M

Hi
thank you. I excuted that program. that's fine. but there is a problem many of my data are read az zero. and dont have their actual value.

The dlmread command will not read in text (must be a numerical value). I am guessing that is the problem. The solution will depend on the file. I will need more information about what is actually causing your problem. create a small file with just a line that is giving you trouble and we can work from there.
