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?!!

[Oleg Komarov]

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

[SARAH ZAVAREH]

Hi Oleg,

What about left hand side of this command?

???=textscan(fid,['%s' repmat('%f',1,255)]);

[Gerd]

On the left hand side is your variable

[Jan]

Data = textscan(fid,['%s' repmat('%f',1,255)]);

Then Data is a cell, which contains the different columns as elements. See "help textscan".
