I met a question about dlmread. the .dat file I have, opened with notepad is like below:
however when I open in MALTAB with dlmread('ckcont.txt'), it appears like below:
definitely difference, expecially at column 1.
however when I use load('ckcont4.txt'), the result seems good.
so I want know is there any difference, or a bug there? I sweep about 1 million of such data in more than one week...what a desperate day!
thanks!

"is there any difference,"
Between Notepad++ and Microsoft Notepad there is a huge difference! When you tell us incorrect information then it makes it harder for us to help you.

You have some corrupt numbers in there, like "-3.3150-109", that seem to be missing the "E". Also, I'm not sure dlmread() understands exponential notation. You can use importdata instead, after you fix the bad entries that are missing "E"s.
data = importdata('ckcont4.txt', ' ');

"is there any difference between them?"
They are different functions: they read different kinds of data, they can read different kinds of file formats, they accept different input arguments, they have different output arguments, they throw different errors for different problems, they have different use cases, they have different limitations, they work at different speeds, they support different output classes, they are written differently,...
oh, and some of them read an open file, some rely on a filename.
