Best Answer

Do you want to get a whole line or a whole column?
Column:
>> fid=fopen('test.txt');
>> A=textscan(fid,'%d %d %d %f %d %f %s','headerlines',1);
>> A{3}
ans =
             1
           512
             1
             8
             8
Line:
A=textscan(fid,'%f %f %f %f %f %f %s','headerlines',1);
>> B=cell2mat(A(1:end-1));
>> B(3,:)
ans =
      3.0000    3.0000    1.0000    1.0000    1.0000  136.3340
