What do you mean by "no result"? What value does fid have? This little test works fine!
str = '2.6300000000000000e+002 2.2500000000000000e+002';
cac = textscan( str,'%f %f');
>> cac{:}
ans =
263
ans =
225

What result do you get from textscan() ? Do you get an error message?

thank u i got it
the code is
function [c]= file11(arg)
fi=fopen(arg,'r');
c=textscan(fi,'%f %f');
fclose(fi);
main file is
fid = fopen('test.txt');
tline = fgetl(fid);
k=1;
images = cell(1, 2);
while ischar(tline)
disp(tline)
images{k}= file11(tline);
k=k+1;
tline = fgetl(fid);
end
disp([images{:}]);
fclose(fid);
it reads given no of files and it stores the contents in cell array
