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?

[Doug Hull]

What is a .CEP file?

[Yasmin Tamimi]

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.

[Andrew Newell]

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.

[Andrew Newell]

By the way - you never use disp to read a file.

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

[Walter Roberson]

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.

[Yasmin Tamimi]

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??

[Walter Roberson]

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.

Answer 1

[Oleg Komarov]

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

[Yasmin Tamimi]

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.

[Walter Roberson]

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.

[Yasmin Tamimi]

OK. now i got it. Thanx a lot for both of you.
