Hi Sarah,
depending on your specific file you can use
fid= fopen('File.txt');
textscan(fid,'%s%f.....');
fclose(fid);

Hi Gerd,
Thanks for your answer.
My problem is that I have 255 columns of %f(numeric). How I can mention this larg number of %f in this command?!!

['%s' repmat('%f',1,255)]

Hi Oleg,
What about left hand side of this command?
???=textscan(fid,['%s' repmat('%f',1,255)]);

On the left hand side is your variable

Data = textscan(fid,['%s' repmat('%f',1,255)]);
Then Data is a cell, which contains the different columns as elements. See "help textscan".
