how save diplayed data?

hi,

i have the following code:

fid=fopen('webscopG.txt');
for j=1:100000
   tline = fgetl(fid);
   i=i+1;
   if ~ischar(tline), break, end
   disp(tline);
end
fclose(fid);

this code will display tline as array, and that what I need . But how I can save this array of tline.

thanks

Save it how? In a different text file? In a .mat file?

text file

If you are unable to modify that source, then consider the diary command, or consider executing that source within evalc() and writing out the characters you get back from evalc().

Much better would be to follow IA's suggestion of writing to a file within the loop itself. fopen(), fprintf(), eventually fclose()

[Walter Roberson]

fid=fopen('webscopG.txt');

outfid=fopen('webscopOut.txt','wt');

for j=1:100000

tline = fgetl(fid);

if ~ischar(tline), break, end

i=i+1;

fprintf(outfid, '%s\n', tline);

end

fclose(fid);

fclose(outfid);

I can not because tline save just last line

I don't see why Walter's code wouldn't work. Maybe you should just try this:

copyfile('webscopG.txt', 'webscopG_Copy.txt');

After all, you're simply just transferring lines.

Huda, notice that tline is fprintf()'d within the loop, not after the loop.

If you want a variable to contain all of the lines after the loop, store tline into a cell array.

fid=fopen('webscopG.txt'); 
for j=1:100000 
tline{i} = fgetl(fid); 
i=i+1; 
if ~ischar(tline), 
break, 
end 
disp(tline); 
end fclose(fid);

does that work?

[Walter Roberson]

No, you cannot have "fclose" in the same statement as "end".

Maybe open a second file for writing and write it out with fprintf()?

[huda nawaf]

I can not do that, because the tline save just last line
