Hi,
I have a text file called File.1.node which contain such as:
45 12 7 1 ( first line )
1 2 1 1
2 3 2 1
3 4 5 1
.....
% File.1.node is complete (last line )
I want to take the data from File.1.node without first line and last line, to put it in another file named Node.dat.
But How i write a code for this problem?
Thanks in advance.

Try this —
fidi = fopen('File.1.node','rt');
F1c = textscan(fidi, '%f%f%f%f', 'HeaderLines',1, 'CollectOutput',1);
fclose(fidi);
F1 = cell2mat(F1c);
dlmwrite(F1, 'Node.dat')
.

@Stephen — Thank you.
The other answer was originally accepted, and I deleted my original (correct) answer as the result. I got an e-mail requesting that I re-post it so that it could be accepted. I did it from memory, and did not remember the correct argument order to dlmwrite (correct in my original answer) because I rarely used it even before writematrix appeared. (My original answer used readmatrix and writematrix, however A Achbak does not have access to them. The dlmwrite call appeared in a subsequent Comment.)

See what readmatrix gives you
m=readmatrix('File.1.node.txt');
m(1,:)=[];
writematrix(m,'Node.dat');
If you do not attach the file, we cannot test.

What about this?
m=dlmread('File.1.node',' ',[1 0 592 3]);
