color=#000000>Ramachandran,</FONT></FONT></DIV>
<DIV> </DIV>
<DIV>Thank you very much! That's exactly what I want. The main problem is that I
only know read('filename.txt', m, n) statement, and it could not work for data
mixed with characters. I tried a lot and never find read statemtne like
A=read("data.txt",-1,1,"(a)"). It helps a lot.</DIV>
<DIV> </DIV>
<DIV>I kind of solved this problem by using file statement:</DIV>
<DIV> </DIV>
<DIV>A =[]; B=[]; C=[];<BR>v=file('open', 'data.txt', 'old');<BR>for i =
1:36000<BR> if i<=12 then Head=fscanf(v,
'%s'); // there is 12
headlines;<BR> else [AA BB CC]=fscanf(v, '%f %f
%f');<BR> A=[A; AA]; B=[B; BB]; C=[C;
CC];<BR>end<BR>end</DIV>
<DIV><FONT face=Verdana color=#000080 size=2>// the data I want is</FONT></DIV>
<DIV><FONT face=Verdana color=#000080 size=2> [A, B, C]</FONT></DIV>
<DIV><FONT face=Verdana color=#000080 size=2></FONT> </DIV>
<DIV><FONT color=#000080>Your read statement is so good that I do not have to
write so long a program. I really appreciate your help.</FONT></DIV>
<DIV><FONT color=#000080>Thanks much and have a great day,</FONT></DIV>
