read different file formats then return their values

How can I read (.CEP) file format through matlab. I tried fscanf and then disp. fscanf is not working and disp always displays -1 for all my .CEP files!!!
So, what command cann I use to read them?

What is a .CEP file?
speech signals are preprocessed in order to be time variant and then we get their cepestrum features for the purpose of speaker recognition. I took it in a speech signal course.
Can you open the file in an ordinary text editor? If you could post a sample of the contents of such a file, it would help.
By the way - you never use disp to read a file.
This is one of the files:

and for the display i first wrote
fid=fopen('N1RONNO.CEP','r')
disp(fid)
and i always got -1 which is wrong and now i knew why, so thnx
Possibly the fopen() is case-sensitive for the file name -- or possibly those should be zeros instead of capital-O.
When fid is -1 that indicates that the fopen() failed. You can use
[fid,message] = fopen('N1RONNO.CEP','r');
and then look at the message to see why the open failed.
It seems like I was putting the files in the wrong directory, but now when I run the command [fid,message] = fopen('N1RONNO.CEP','r');
fid returns only one number instead of the matrix??
fid will only be a file identifier. You will need to textscan() or fscanf() or the like to read the data. See Oleg's example.

fid = fopen('fullpath/namefile.cep'); % In read mode by default
data = textscan(fid,repmat('%f',1,15),'Delimiter',' ');
fid = fclose(fid);
Substitute 'fullpath/namefile.cep' with your path and the name of the file

Thnx Oleg. I tried ur example but when i wrote data it only gave me the dimensions,, so I really don't know what it really does.
I tried load and it worked.
textscan() returns a cell array.
If you change Oleg's textscan() to
data = textscan(fid,repmat('%f',1,15),'Delimiter',' ','CombineOutput',true);
then afterwards data{1} will be the entire matrix of data.
OK. now i got it. Thanx a lot for both of you.
